Janus  Money  Market  Fund,  Janus  Government  Money  Market  Fund,  and  Janus
Tax-Exempt  Money Market Fund  (individually,  a "Fund" and,  collectively,  the
"Funds") are designed for investors who seek maximum  current income  consistent
with stability of capital.  This prospectus offers a separate class of shares of
each Fund  (collectively,  the  "Shares")  exclusively  through  banks and other
financial  institutions  ("Financial  Institutions")  in  connection  with trust
accounts,  cash  management  programs  and  similar  programs  provided to their
customers.  Each  Fund is a  separate  series  of  Janus  Investment  Fund  (the
"Trust"), an open-end management investment company.

Each Fund invests  exclusively  in high quality  money  market  instruments.  AN
INVESTMENT IN A FUND IS NEITHER  INSURED NOR GUARANTEED BY THE U.S.  GOVERNMENT.
THERE IS NO  ASSURANCE  THAT A FUND WILL BE ABLE TO  MAINTAIN A STABLE NET ASSET
VALUE OF $1.00 PER SHARE.

The Shares are offered with no sales charges, commissions, redemption fees, Rule
12b-1 fees or deferred sales  charges.  There is a $250,000  initial  investment
minimum by each Financial  Institution.  The Financial Institution may aggregate
investments by all of its customers to achieve this minimum. There is no minimum
amount  required for  subsequent  investments.  For  complete  details on how to
purchase,  redeem  and  exchange  Shares,  please  see the  Shareholder's  Guide
beginning at page 9.

   
This prospectus contains information about the Shares that prospective investors
should consider  before  investing and should be read carefully and retained for
future  reference.  Additional  information about the Shares is contained in the
Statement of Additional  Information  ("SAI") dated November 22, 1996,  which is
filed with the Securities and Exchange Commission ("SEC") and is incorporated by
reference  into this  Prospectus.  The SAI is available upon request and without
charge by writing or calling your Financial Institution.
    

THE SHARES  OFFERED BY THIS  PROSPECTUS  ARE NOT DEPOSITS OR  OBLIGATIONS OF ANY
BANK,  ARE NOT ENDORSED OR  GUARANTEED  BY ANY BANK,  AND ARE NOT INSURED BY THE
FEDERAL DEPOSIT INSURANCE  CORPORATION,  THE FEDERAL RESERVE BOARD, OR ANY OTHER
GOVERNMENT AGENCY.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY STATE
SECURITIES  COMMISSION NOR HAS THE SEC OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE  ACCURACY OR ADEQUACY OF THIS  PROSPECTUS.  ANY  REPRESENTATION  TO THE
CONTRARY IS A CRIMINAL OFFENSE.

THIS  PROSPECTUS DOES NOT CONSTITUTE AN OFFER TO SELL SECURITIES IN ANY STATE OR
OTHER JURISDICTION TO ANY PERSON TO WHOM IT IS UNLAWFUL TO MAKE SUCH AN OFFER IN
SUCH STATE OR OTHER JURISDICTION.

(1)  The fees and  expenses in the table above are based on the  estimated  fees
     and expenses that the Service  Shares of the Funds expect to incur in their
     initial  fiscal  year,  net of fee  waivers  from the  investment  adviser.
     Without  such  waivers,  the  Management  Fee,  Other  Expenses  and  Total
     Operating  Expenses for Service Shares are estimated to be 0.20%, 0.40% and
     0.60%,  respectively.  Janus Capital may modify or terminate the waivers at
     any time upon 90 days' notice to the Trustees.  See "Investment Adviser and
     Administrator" for a more detailed discussion of the fees.
(2)  A portion of the administration fee included in "other expense" may be used
     to compensate Financial Institutions for providing  administrative services
     to their customers who invest in the Shares. See  "Administrator"  for more
     details. Certain Financial Institutions may charge additional fees directly
     to their customers for other services.  Consult your Financial  Institution
     to determine whether it charges any additional fees.

FINANCIAL HIGHLIGHTS

No Financial  Highlights are presented for the Shares because the Shares did not
commence operations before the date of this prospectus.

INVESTMENT OBJECTIVES, POLICIES AND TECHNIQUES

Unless  otherwise  stated,  the investment  objectives and policies set forth in
this  Prospectus are not  fundamental  and may be changed by the Trustees of the
Trust  (the  "Trustees")  without  shareholder  approval.  Shareholders  will be
notified of material changes in investment objectives or policies. If there is a
change in the investment objective or policies of any Fund,  shareholders should
consider  whether that Fund remains an appropriate  investment in light of their
then current  financial  position and needs. The Funds are subject to additional
investment  policies and  restrictions  described in the SAI,  some of which are
fundamental and may not be changed without shareholder approval.

INVESTMENT OBJECTIVES

The investment  objective of Janus Money Market Fund and Janus  Government Money
Market Fund is to seek  maximum  current  income to the extent  consistent  with
stability of capital.  The investment objective of Janus Tax-Exempt Money Market
Fund is to seek maximum  current income that is exempt from federal income taxes
to the extent  consistent  with stability of capital.  There can be no assurance
that a Fund will  achieve its  investment  objective  or that the Shares will be
able to maintain a stable net asset value of $1.00 per share.

COMMON INVESTMENT POLICIES

The Funds will invest only in eligible  high  quality,  short-term  money market
instruments  that present  minimal credit risks,  as determined by Janus Capital
Corporation,  the Funds'  investment  adviser  ("Janus  Capital"),  pursuant  to
procedures  adopted  by  the  Trustees.  Each  Fund  may  invest  only  in  U.S.
dollar-denominated  instruments  that have a  remaining  maturity of 397 days or
less (as calculated  pursuant to Rule 2a-7 under the  Investment  Company Act of
1940  ("1940  Act"))  and will  maintain  a  dollar-weighted  average  portfolio
maturity of 90 days or less.

   
Except  to the  limited  extent  permitted  by Rule  2a-7  and  except  for U.S.
Government Securities (as defined below), each Fund will not invest more than 5%
of its total  assets in the  securities  of any one issuer.  A guarantor  is not
considered  an issuer for the purpose of this limit,  provided that the value of
all securities held by a Fund that are issued or guaranteed by that  institution
does not exceed 10% of the Fund's total assets. Until pending amendments to Rule
2a-7 become effective,  up to 25% of Janus Tax-Exempt Money Market Fund's assets
may be invested  without  regard to the  foregoing  limitations.  A Fund may not
invest more than 25% of its total assets in any one  industry,  except that this
limit  does  not  apply  to U.S.  Government  Securities,  bank  obligations  or
municipal securities. To ensure adequate liquidity, no Fund may invest more than
10% of its net assets in illiquid  investments,  including repurchase agreements
maturing  in more than  seven days  (unless  subject  to a demand  feature)  and
certain time deposits that are subject to early withdrawal  penalties and mature
in more  than  seven  days.  Because  the  Funds  are  typically  used as a cash
management  vehicle,  they intend to maintain a high degree of liquidity.  Janus
Capital determines and monitors the liquidity of portfolio  securities under the
supervision of the Trustees.
    

RATINGS.
High quality money market  instruments  include those that (i) are rated (or, if
unrated,  are issued by an issuer with  comparable  outstanding  short-term debt
that is rated) in one of the two highest rating  categories for short-term  debt
by any two nationally recognized statistical rating organizations ("NRSROs") or,
if only one  NRSRO  has  issued a rating,  by that  NRSRO or (ii) are  otherwise
unrated and determined by Janus Capital to be of comparable quality.  Each Fund,
except Janus Tax-Exempt Money Market Fund, will invest at least 95% of its total
assets in securities in the highest rating  category (as determined  pursuant to
Rule 2a-7).  Descriptions of the rating  categories of Standard & Poor's Ratings
Services,  Moody's  Investors  Service,  Inc.,  and  certain  other  NRSROs  are
contained  in the SAI,  as is a further  description  of the  Funds'  investment
policies.

Although  each Fund only invests in high quality  money market  instruments,  an
investment in a Fund is subject to risk even if all  securities in its portfolio
are paid in full at  maturity.  All money  market  instruments,  including  U.S.
Government  Securities,  can change in value as a result of changes in  interest
rates, the issuer's actual or perceived creditworthiness or the issuer's ability
to meet its obligations.

TYPES OF INVESTMENTS

JANUS MONEY MARKET FUND

Janus Money  Market Fund pursues its  objective  by investing  primarily in high
quality debt obligations and obligations of financial institutions. The Fund may
also  invest in U.S.  Government  Securities  (as defined  below) and  municipal
securities,  although the Fund expects to invest in such  securities to a lesser
degree.

DEBT OBLIGATIONS.
The  Fund  may  invest  in  debt  obligations  of  domestic  issuers,  including
commercial  paper  (short-term  promissory  notes issued by companies to finance
their, or their affiliates', current obligations), notes and bonds, and variable
amount master demand notes. The payment  obligations on these instruments may be
backed by  securities,  swap  agreements or other assets,  by the guarantee of a
third party or solely by the  unsecured  promise of the issuer to make  payments
when due.  The Fund may invest in  privately  issued  commercial  paper or other
securities  that are restricted as to disposition  under the federal  securities
laws. In general,  sales of these securities may not be made absent registration
under the  Securities  Act of 1933 (the "1933  Act") or the  availability  of an
appropriate  exemption  therefrom.  Pursuant to Section  4(2) of the 1933 Act or
Rule 144A adopted  under the 1933 Act,  however,  some of these  securities  are
eligible for resale to institutional investors,  and accordingly,  Janus Capital
may  determine  that a liquid  market  exists  for such a security  pursuant  to
guidelines adopted by the Trustees.

<PAGE>
OBLIGATIONS OF FINANCIAL INSTITUTIONS.
The Fund may  invest in  obligations  of  financial  institutions.  Examples  of
obligations  in which the Fund may invest  include  negotiable  certificates  of
deposit, bankers' acceptances and time deposits of U.S. banks (including savings
and loan associations)  having total assets in excess of one billion dollars and
U.S.  branches of foreign  banks  having  total  assets in excess of ten billion
dollars.  The Fund may also invest in Eurodollar and Yankee bank  obligations as
discussed below.

Certificates  of deposit  represent an  institution's  obligation to repay funds
deposited  with it that earn a  specified  interest  rate  over a given  period.
Bankers'  acceptances are negotiable  obligations of a bank to pay a draft which
has been drawn by a customer  and are usually  backed by goods in  international
trade. Time deposits are non-negotiable deposits with a banking institution that
earn a specified interest rate over a given period.  Fixed time deposits,  which
are  payable  at a  stated  maturity  date and  bear a fixed  rate of  interest,
generally  may be  withdrawn  on demand by the Fund but may be  subject to early
withdrawal  penalties  that could  reduce the Fund's  yield.  Unless  there is a
readily  available  market for them,  time  deposits  that are  subject to early
withdrawal  penalties and that mature in more than seven days will be treated as
illiquid securities.

EURODOLLAR OR YANKEE OBLIGATIONS.
The Fund may invest in Eurodollar and Yankee bank  obligations.  Eurodollar bank
obligations  are  dollar-denominated  certificates  of deposit or time  deposits
issued outside the U.S. capital markets by foreign branches of U.S. banks and by
foreign banks. Yankee bank obligations are dollar-denominated obligations issued
in the U.S. capital markets by foreign banks.

Eurodollar  (and to a limited  extent,  Yankee) bank  obligations are subject to
certain  sovereign  risks.  One  such  risk is the  possibility  that a  foreign
government  might  prevent  dollar-denominated  funds  from  flowing  across its
borders.  Other risks include:  adverse political and economic developments in a
foreign  country;  the extent and quality of government  regulation of financial
markets and  institutions;  the  imposition of foreign  withholding  taxes;  and
expropriation or nationalization of foreign issuers.

U.S. GOVERNMENT SECURITIES.
The Fund may invest  without  limit in U.S.  Government  Securities as described
below under "Janus Government Money Market Fund."

MUNICIPAL SECURITIES.
The Fund may invest in obligations of states,  territories or possessions of the
United States and their subdivisions,  authorities and corporations as described
below under "Janus  Tax-Exempt  Money Market  Fund." These  obligations  may pay
interest that is exempt from federal income taxation.

JANUS GOVERNMENT MONEY MARKET FUND

Janus   Government   Money  Market  Fund  pursues  its  objective  by  investing
exclusively in obligations issued and/or guaranteed as to principal and interest
by the United  States  government or by its agencies and  instrumentalities  and
repurchase agreements secured by such obligations.

U.S. GOVERNMENT SECURITIES.
U.S. Government Securities shall have the meaning set forth in the 1940 Act. The
1940 Act defines U.S.  Government  Securities  to include  securities  issued or
guaranteed  by the U.S.  government,  its agencies and  instrumentalities.  U.S.
Government Securities may also include repurchase  agreements  collateralized by
and  municipal  securities  escrowed  with  or  refunded  with  U.S.  government
securities. U.S. Government Securities in which the Fund may invest include U.S.
Treasury  securities  and  obligations  issued or guaranteed by U.S.  government
agencies and  instrumentalities  that are backed by the full faith and credit of
the  U.S.   government,   such  as  those   guaranteed  by  the  Small  Business
Administration  or issued by the Government  National Mortgage  Association.  In
addition,  U.S.  Government  Securities  in which  the Fund may  invest  include
securities  supported primarily or solely by the creditworthiness of the issuer,
such as securities of the Federal  National  Mortgage  Association,  the Federal
Home Loan Mortgage  Corporation and the Tennessee Valley Authority.  There is no
guarantee  that the U.S.  government  will support  securities not backed by its
full faith and credit. Accordingly,  although these securities have historically
involved little risk of loss of principal if held to maturity,  they may involve
more  risk than  securities  backed  by the full  faith  and  credit of the U.S.
government.

JANUS TAX-EXEMPT MONEY MARKET FUND

Janus Tax-Exempt Money Market Fund pursues its objective by investing  primarily
in municipal  securities  whose  interest is exempt from federal  income  taxes,
including the federal alternative minimum tax. Although the Fund will attempt to
invest substantially all of its assets in municipal securities whose interest is
exempt from federal  income  taxes,  the Fund reserves the right to invest up to
20% of the value of its net assets in  securities  whose  interest is  federally
taxable. Additionally, when its portfolio manager is unable to locate investment
opportunities with desirable  risk/reward  characteristics,  the Fund may invest
without limit in cash and cash  equivalents,  including  obligations that may be
federally taxable (see "Taxable Investments").

MUNICIPAL SECURITIES.
The municipal  securities in which the Fund may invest include  municipal  notes
and short-term  municipal  bonds.  Municipal notes are generally used to provide
for the issuer's  short-term  capital needs and generally have maturities of 397
days or less. Examples include tax anticipation and revenue  anticipation notes,
which generally are issued in anticipation of various  seasonal  revenues,  bond
anticipation  notes,  construction  loan notes and tax-exempt  commercial paper.
Short-term  municipal bonds may include  "general  obligation  bonds," which are
secured by the issuer's pledge of its faith, credit and taxing power for payment
of principal and interest;  "revenue  bonds," which are generally  paid from the
revenues of a particular  facility or a specific excise tax or other source; and
"industrial  development  bonds,"  which  are  issued  by or on behalf of public
authorities


   
JANUS MONEY MARKET FUNDS - SERVICE SHARES PROSPECTUS           November 22, 1996
    
                                       3

<PAGE>
to provide  funding for various  privately  operated  industrial  and commercial
facilities.  The Fund may also invest in high quality participation interests in
municipal securities.  A more detailed description of various types of municipal
securities is contained in Appendix B in the SAI.

When the assets and revenues of an agency,  authority,  instrumentality or other
political  subdivision  are separate from those of the  government  creating the
issuing  entity and a security is backed only by the assets and  revenues of the
issuing  entity,  that  entity  will be  deemed  to be the  sole  issuer  of the
security.  Similarly,  in the case of an industrial development bond backed only
by the assets and revenues of the non-governmental  issuer, the non-governmental
issuer will be deemed to be the sole issuer of the bond.

At times,  the Fund may invest more than 25% of the value of its total assets in
tax-exempt securities that are related in such a way that an economic, business,
or political  development or change  affecting one such security could similarly
affect the other securities;  for example,  securities whose issuers are located
in the same state,  or  securities  whose  interest is derived from  revenues of
similar type  projects.  The Fund may also invest more than 25% of its assets in
industrial development bonds or participation interests therein.

Yields on municipal securities are dependent on a variety of factors,  including
the  general  conditions  of the  money  market  and of the  municipal  bond and
municipal note markets, the size of a particular  offering,  the maturity of the
obligation and the rating of the issue. The achievement of the Fund's investment
objective  is  dependent  in part on the  continuing  ability of the  issuers of
municipal securities in which the Fund invests to meet their obligations for the
payment of principal and interest when due.  Obligations of issuers of municipal
securities  are subject to the  provisions of  bankruptcy,  insolvency and other
laws  affecting  the rights and remedies of  creditors,  such as the  Bankruptcy
Reform Act of 1978, as amended.  Therefore,  the  possibility  exists that, as a
result of litigation or other conditions, the ability of any issuer to pay, when
due, the principal of and interest on its municipal securities may be materially
affected.

MUNICIPAL LEASES.
The Fund may invest in  municipal  leases or  participation  interests  therein.
Municipal leases are municipal  securities which may take the form of a lease or
an installment  purchase or conditional  sales  contract.  Municipal  leases are
issued by state and local  governments and authorities to acquire a wide variety
of equipment and facilities.  Lease obligations may not be backed by the issuing
municipality's credit and may involve risks not normally associated with general
obligation bonds and other revenue bonds. For example, their interest may become
taxable if the lease is assigned  and the holders may incur losses if the issuer
does not appropriate  funds for the lease payment on an annual basis,  which may
result in  termination  of the lease and  possible  default.  Janus  Capital may
determine that a liquid market exists for municipal lease  obligations  pursuant
to guidelines established by the Trustees.

TAXABLE INVESTMENTS.
As discussed above,  although the Fund will attempt to invest  substantially all
of its assets in  municipal  securities  whose  interest is exempt from  federal
income  tax,  the  Fund  may  under  certain  circumstances  invest  in  certain
securities whose interest is subject to such taxation. These securities include:
(i)   short-term   obligations   of  the  U.S.   government,   its  agencies  or
instrumentalities,  (ii)  certificates  of  deposit,  bankers'  acceptances  and
interest-bearing  savings deposits of banks having total assets of more than one
billion dollars and whose deposits are insured by the Federal Deposit  Insurance
Corporation,  (iii) commercial paper and (iv) repurchase agreements as described
below covering any of the securities  described in items  (i)-(iii) above or any
other obligations of the U.S. government, its agencies or instrumentalities.

COMMON INVESTMENT TECHNIQUES

PARTICIPATION INTERESTS.
The Funds may invest in participation interests in any type of security in which
the  Funds  may  invest.  A  participation  interest  gives a Fund an  undivided
interest  in  the  underlying  securities  in the  proportion  that  the  Fund's
participation  interest  bears to the total  principal  amount of the underlying
securities. Participation interests usually carry a demand feature, as described
below,  backed by a letter of credit or guarantee of the institution that issued
the interests permitting the holder to tender them back to the institution.

DEMAND FEATURES.
The Funds  may  invest  in  securities  that are  subject  to puts and  stand-by
commitments  ("demand  features").  Demand  features  give the Fund the right to
resell  securities  at specified  periods prior to their  maturity  dates to the
seller or to some third party at an agreed-upon price or yield.  Securities with
demand features may involve certain expenses and risks,  including the inability
of the  issuer  of the  instrument  to pay for the  securities  at the  time the
instrument is exercised,  non-marketability  of the instrument  and  differences
between  the  maturity  of the  underlying  security  and  the  maturity  of the
instrument.  Securities  may cost more with demand  features  than without them.
Demand features can serve three purposes:  to shorten the maturity of a variable
or floating rate  security,  to enhance the  instrument's  credit quality and to
provide a source of liquidity.  Demand  features are often issued by third party
financial institutions,  generally domestic and foreign banks. Accordingly,  the
credit quality and liquidity of the Funds'  investments may be dependent in part
on the credit quality of the banks supporting the Funds' investments.  This will
result in exposure to risks  pertaining to the banking  industry,  including the
foreign banking industry.  Brokerage firms and insurance  companies also provide
certain  liquidity  and  credit  support.  A  substantial  portion  of the Janus
Tax-Exempt Money Market Fund's portfolio in particular may consist of securities
backed by banks and other  financial  institutions,  and thus adverse changes in
the credit  quality of these  institutions  could  cause  losses to the Fund and
affect its share price.

VARIABLE AND FLOATING RATE SECURITIES.
The  securities in which the Funds invest may have variable or floating rates of
interest.  These securities pay interest


   
JANUS MONEY MARKET FUNDS - SERVICE SHARES PROSPECTUS           November 22, 1996
    
                                       4

<PAGE>
at rates  that are  adjusted  periodically  according  to a  specified  formula,
usually with  reference to some  interest  rate index or market  interest  rate.
Securities  with  ultimate  maturities of greater than 397 days may be purchased
only pursuant to Rule 2a-7.  Under that Rule, only those  long-term  instruments
that have demand  features  which comply with certain  requirements  and certain
variable rate U.S. Government Securities may be purchased. Similar to fixed rate
debt instruments,  variable and floating rate instruments are subject to changes
in value based on changes in market interest rates or changes in the issuer's or
guarantor's creditworthiness.  The rate of interest on securities purchased by a
Fund may be tied to  short-term  Treasury  or  other  government  securities  or
indices on securities that are permissible  investments of the Funds, as well as
other money  market rates of  interest.  The Funds will not purchase  securities
whose values are tied to interest rates or indices that are not  appropriate for
the duration and volatility standards of a money market fund.

MORTGAGE- AND
ASSET-BACKED SECURITIES.
Janus Money  Market Fund and Janus  Government  Money  Market Fund may  purchase
fixed or adjustable  rate  mortgage-backed  securities  issued by the Government
National  Mortgage  Association,  Federal  National  Mortgage  Association,  the
Federal   Home   Loan   Mortgage   Corporation,   or   other   governmental   or
government-related  entities. In addition,  Janus Money Market Fund may purchase
other asset-backed securities,  including securities backed by automobile loans,
equipment  leases or credit  card  receivables.  These  securities  directly  or
indirectly  represent a  participation  in, or are secured by and payable  from,
fixed or  adjustable  rate  mortgage or other loans which may be secured by real
estate or other assets.  Unlike traditional debt instruments,  payments on these
securities include both interest and a partial payment of principal. Prepayments
of the  principal of underlying  loans may shorten the  effective  maturities of
these securities and may result in a Fund having to reinvest proceeds at a lower
interest rate.

REPURCHASE AGREEMENTS.
Each Fund may seek additional income by entering into collateralized  repurchase
agreements.  Repurchase  agreements are  transactions  in which a Fund purchases
securities and  simultaneously  commits to resell those securities to the seller
at an agreed-upon price on an agreed-upon future date. The resale price reflects
a market rate of interest  that is not related to the coupon rate or maturity of
the  purchased  securities.  If  the  seller  of  the  securities  underlying  a
repurchase agreement fails to pay the agreed resale price on the agreed delivery
date, a Fund may incur costs in disposing of the  collateral  and may experience
losses if there is any delay in its ability to do so.

REVERSE REPURCHASE AGREEMENTS.
Each Fund may enter  into  reverse  repurchase  agreements.  Reverse  repurchase
agreements are transactions in which a Fund sells a security and  simultaneously
commits to repurchase that security from the buyer at an agreed upon price on an
agreed upon future  date.  This  technique  will be used only for  temporary  or
emergency purposes,  such as meeting redemption requests,  or to earn additional
income on portfolio securities.

DELAYED DELIVERY SECURITIES.
Each Fund may purchase  securities on a when-issued or delayed  delivery  basis.
Securities so purchased are subject to market price fluctuation from the time of
purchase but no interest on the securities  accrues to a Fund until delivery and
payment for the securities take place. Accordingly,  the value of the securities
on the  delivery  date may be more or less  than  the  purchase  price.  Forward
commitments  will be entered  into only when a Fund has the  intention of taking
possession  of the  securities,  but a Fund may sell the  securities  before the
settlement date if deemed advisable.

BORROWING AND LENDING.
Each Fund may borrow money for temporary or emergency  purposes in amounts up to
25% of its total assets. A Fund may not mortgage or pledge  securities except to
secure  permitted  borrowings.  As a  fundamental  policy,  a Fund will not lend
securities  or other  assets if, as a result,  more than 25% of its total assets
would be lent to other parties;  however,  the Funds do not currently  intend to
engage in securities lending.  Each Fund intends to seek permission from the SEC
to borrow money from or lend money to other funds that permit such  transactions
and are advised by Janus  Capital.  There is no assurance  that such  permission
will be granted.



INVESTMENT ADVISER AND ADMINISTRATOR

INVESTMENT ADVISER

Each Fund has a separate Investment  Advisory Agreement with Janus Capital,  100
Fillmore  Street,  Denver,  Colorado  80206-4923.  Janus  Capital  has served as
investment  adviser to Janus Fund since 1970 and currently  serves as investment
adviser to all of the Janus  funds,  as well as adviser or  subadviser  to other
mutual funds and  individual,  corporate,  charitable and  retirement  accounts.
Kansas City Southern  Industries,  Inc., a publicly traded holding company whose
primary subsidiaries are engaged in transportation,  information  processing and
financial  services  ("KCSI"),  owns approximately 83% of the outstanding voting
stock of Janus  Capital.  Thomas H. Bailey,  the  President  and Chairman of the
Board of Janus  Capital,  owns  approximately  12% of its voting  stock and,  by
agreement with KCSI, selects a majority of Janus Capital's Board.


   
JANUS MONEY MARKET FUNDS - SERVICE SHARES PROSPECTUS           November 22, 1996
    
                                       5

<PAGE>
Pursuant  to  the  Investment  Advisory  Agreements,   Janus  Capital  furnishes
continuous advice and recommendations  concerning each Fund's investments.  Each
of the Funds has agreed to compensate Janus Capital for its advisory services by
the  monthly  payment of a fee at the  annual  rate of 0.20% of the value of the
average  daily net  assets of each  Fund.  Janus  Capital  has agreed to waive a
portion  of its fee and  accordingly,  the  advisory  fee of each  Fund  will be
calculated at the annual rate of 0.10% of the value of each Fund's average daily
net assets. Janus Capital may modify or terminate the waiver at any time upon 90
days' notice to the Trustees.

ADMINISTRATOR

Each of the Funds has also entered into an  Administration  Agreement with Janus
Capital,  pursuant  to which Janus  Capital  furnishes  certain  administrative,
compliance  and  accounting  services for the Funds,  pays the costs of printing
reports and  prospectuses for existing  shareholders,  provides office space for
the Funds and pays the  salaries,  fees and expenses of all Fund officers and of
those Trustees who are affiliated  with Janus Capital.  Administrative  services
provided by Janus Capital under the  Administration  Agreements  include custody
and transfer  agency  services.  Janus  Capital is paid an  administration  fee,
calculated  daily and paid monthly,  at the annual rate of 0.40% of the value of
the average  daily net assets of each Fund  attributable  to Shares for services
rendered pursuant to the Administration Agreements.  Janus Capital has agreed to
waive a portion of its fee and accordingly,  the  administration fee paid by the
Shares  will be  calculated  at the  annual  rate of 0.30% of the  value of each
Fund's average daily net assets  attributable  to the Shares.  Janus Capital may
modify  or  terminate  this  waiver  at any  time  upon 90 days'  notice  to the
Trustees.

Each Fund pays all of its  expenses  not  assumed  by Janus  Capital,  including
auditing fees and independent Trustees' fees and expenses.

Janus Capital may use all or a portion of its  administration  fee to compensate
Financial Institutions for providing  administrative services to their customers
who invest in the Shares. The types of services that the Financial  Institutions
would provide  include  serving as the sole  shareholder of record,  shareholder
recordkeeping,  processing and aggregating purchase and redemption transactions,
providing  periodic  statements,   forwarding   shareholder  reports  and  other
materials,  providing tax information, and providing other similar services that
the  Funds  would  have to  perform  if they  were  dealing  directly  with  the
beneficial owners,  rather than the Financial  Institutions,  as shareholders of
record.

The Glass-Steagall Act prohibits a depository  institution (such as a commercial
bank or a savings and loan association) from being an underwriter or distributor
of most securities.  In the event the  Glass-Steagall  Act is deemed to prohibit
depository  institutions from acting in the administrative  capacities described
above or should Congress relax current restrictions on depository  institutions,
the Trustees will consider appropriate changes in the services.

PORTFOLIO TRANSACTIONS

Purchases and sales of securities on behalf of each Fund are executed by brokers
and dealers selected by Janus Capital.  Broker-dealers are selected on the basis
of their ability to obtain best price and execution for the Funds'  transactions
and recognizing brokerage,  research and other services provided to the Fund and
to Janus  Capital.  Janus  Capital may also  consider  payments  made by brokers
effecting  transactions  for a Fund i) to the  Fund or ii) to other  persons  on
behalf  of the  Fund for  services  provided  to the Fund for  which it would be
obligated to pay. The Funds'  Trustees have also  authorized  the Funds to place
portfolio  transactions  on  an  agency  basis  with  a  broker-dealer  that  is
affiliated with Janus Capital.  Agency trades, if any, that are placed with such
affiliated  party serve to reduce certain expenses of the Funds. The SAI further
explains the selection of broker-dealers.

PERSONAL INVESTING

   
Janus Capital does not permit portfolio managers to purchase and sell securities
for their own accounts  except under the limited  exceptions  contained in Janus
Capital's policy governing personal  investing.  Janus Capital's policy requires
investment and other personnel to conduct their personal  investment  activities
in a manner  that Janus  Capital  believes is not  detrimental  to the Funds and
Janus  Capital's  other  advisory  clients.   See  the  SAI  for  more  detailed
information.
    



DISTRIBUTIONS AND TAXES

Dividends  representing  substantially  all of the net investment income and any
net realized gains on sales of securities are declared daily, Saturdays, Sundays
and holidays  included,  and distributed on the last business day of each month.
If a month begins on a Saturday, Sunday or holiday, dividends for those days are
declared at the end of the preceding month and distributed on the first business
day of the month.  Distributions  will be  reinvested in Shares of a Fund unless
otherwise  elected by the  shareholder  pursuant to the  options  offered by the
Financial Institution.

Distributions  for all of the Funds (except Janus  Tax-Exempt Money Market Fund)
are  taxable   income  and  are  subject  to  federal  income  tax  (except  for
shareholders exempt from income tax), whether such distributions are received in
cash or are reinvested in additional Shares. Full


   
JANUS MONEY MARKET FUNDS - SERVICE SHARES PROSPECTUS           November 22, 1996
    
                                       6
<PAGE>
information  regarding the tax status of income  dividends and any capital gains
distributions  will be mailed to  Financial  Institutions  who will  forward the
information  to their  customers  for tax purposes on or before  January 31st of
each year.  Because the Funds are money  market  funds,  they do not  anticipate
making any capital gains distributions.

Janus Tax-Exempt Money Market Fund  anticipates  that  substantially  all income
dividends it pays will be exempt from  federal  income tax.  However,  dividends
attributable  to interest on taxable  investments,  together with  distributions
from any net  realized  capital  gains,  are taxable.  In addition,  interest on
certain  private  activity  bonds  is a  preference  item  for  purposes  of the
individual and corporate  alternative minimum taxes. To the extent that the Fund
earns such income,  shareholders who are subject to the alternative  minimum tax
must include such income as a preference item. The Fund will advise shareholders
of the percentage of dividends, if any, subject to the alternative minimum tax.

Dividends and capital gains distributions may also be subject to state and local
taxes. In certain states some portion of dividends and distributions  (depending
on the sources of the Fund's net income) of Janus  Tax-Exempt  Money Market Fund
may be exempt from state and local taxes.  Shareholders should consult their own
tax advisor regarding exemption from any applicable state and local tax, as well
as the tax treatment of any dividends or distributions from the Shares.

The  Funds  intend  to comply  with  provisions  of the  Internal  Revenue  Code
applicable to investment companies,  and thus it is not expected that any of the
Funds  will be  required  to pay any  federal  income or excise  taxes.  The SAI
further explains the Funds' tax status.



PERFORMANCE

The  Shares  may  measure  performance  in  several  ways,   including  "yield,"
"effective yield," and "tax equivalent yield" (for Janus Tax-Exempt Money Market
Fund  only).  Yield is a way of showing  the rate of income  the Shares  earn on
investments  as a percentage of the Share price.  Yield  represents  the income,
less expenses generated by an investment,  in the Shares over a seven-day period
expressed as an annual percentage rate. Effective yield is similar in that it is
calculated  over the same time frame,  but instead the net investment  income is
compounded and then  annualized.  Due to the compounding  effect,  the effective
yield will normally be higher than the yield.

Shares of Janus  Tax-Exempt  Money  Market  Fund may also  quote  tax-equivalent
yield, which shows the taxable yield an investor would have to earn before taxes
to equal such Shares'  tax-free yield. A  tax-equivalent  yield is calculated by
dividing  such  Shares'  tax-exempt  yield by the  result  of one minus a stated
federal tax rate.  Only that portion of the Fund's  income that is tax-exempt is
adjusted in this calculation.

Performance  figures are based upon  historical  results and are not intended to
indicate future performance.

MISCELLANEOUS INFORMATION

ORGANIZATION

Each Fund is an open-end management investment company registered under the 1940
Act as a series of the Trust,  which was created on February 11, 1986. Each Fund
currently  offers three classes of shares by separate  prospectuses.  The Shares
offered by this  Prospectus  are available only through  Financial  Institutions
that meet minimum  investment  requirements  in connection  with trust accounts,
cash management  programs and similar programs  provided to their  customers.  A
second class of shares, Institutional Shares of each Fund, are available only to
institutional  clients,  including  corporations,  foundations  and trusts,  and
individuals  meeting certain initial investment  requirements.  A third class of
shares,  Investor  Shares of each Fund,  are  available  to the general  public.
Because the expenses of each class may differ,  the performance of each class is
expected  to  differ.  If you would like  additional  information,  please  call
1-800-29JANUS.

TRUSTEES

The Trustees  oversee the business  affairs of the Trust and are responsible for
major decisions relating to each Fund's investment  objective and policies.  The
Trustees delegate the day-to-day  management of the Funds to the officers of the
Trust and meet at least  quarterly  to review  the Funds'  investment  policies,
performance, expenses and other business affairs.

VOTING RIGHTS

The Trust is not required to hold annual shareholder meetings.  However, special
meetings may be called for a specific  class of shares,  a specific Fund, or for
the Trust as a whole,  for  purposes  such as  electing  or  removing  Trustees,
terminating or reorganizing the Trust,  changing  fundamental policies or voting
on matters when required by the 1940 Act. Separate votes are taken by a separate
Fund (or a separate  class of shares)  only if a matter  affects or requires the
vote of just that Fund (or those shares).  Shareholders are entitled to cast one
vote for each Share they own.

CUSTODIAN, TRANSFER AGENT
AND DISTRIBUTOR

United Missouri Bank, N.A., P.O. Box 419226,  Kansas City, Missouri  64141-6226,
is the custodian of the Funds' assets. The custodian holds each Fund's assets in
safekeeping   and  collects  and  remits  the  income  thereon  subject  to  the
instructions of each Fund.

Janus Service  Corporation,  P.O. Box 173375,  Denver,  Colorado  80217-3375,  a

SHAREHOLDER'S GUIDE

INVESTORS MAY NOT PURCHASE OR REDEEM SHARES OF THE FUNDS DIRECTLY. SHARES MAY BE
PURCHASED OR REDEEMED ONLY THROUGH  FINANCIAL  INSTITUTIONS  IN CONNECTION  WITH
TRUST ACCOUNTS,  CASH MANAGEMENT  PROGRAMS AND SIMILAR PROGRAMS.  YOUR FINANCIAL
INSTITUTION  WILL  PROVIDE YOU WITH  INSTRUCTIONS  ON  PURCHASING  OR  REDEEMING
SHARES.

   
The Financial  Institutions are responsible for promptly transmitting  purchase,
redemption and other requests to the Funds under the  arrangements  made between
the Financial  Institutions and their  customers.  The Funds are not responsible
for the failure of any Financial Institution to carry out its obligations to its
customers.
    

PURCHASES

   
Purchases of Fund Shares may be made only through omnibus  accounts of Financial
Institutions  in connection with trust  accounts,  cash management  programs and
similar programs.  Your Financial Institution will provide you with instructions
on  purchasing  Shares.  The  Financial  Institutions  may  impose  charges  and
restrictions   different  from  those  imposed  by  the  Funds.   The  Financial
Institutions  may  also  require   different   minimum  initial  and  subsequent
investments than required by the Funds.
    

All  investments  in  the  Funds  are  credited  to  a  participating  Financial
Institution's  omnibus  account upon  acceptance  of the  investment  by a Fund.
Investments  will be  processed  at the NAV  next  determined  after an order is
received and accepted by a Fund.

Each Fund  reserves the right to reject any specific  purchase  order.  Purchase
orders may be refused if, in Janus  Capital's  opinion,  they are of a size that
would disrupt the  management of a Fund. Any Fund may  discontinue  sales of its
Shares if management  believes that a substantial further increase may adversely
affect that Fund's ability to achieve its investment  objective.  In such event,
however, it is anticipated that existing Financial Institution customers in that
Fund would be permitted to continue to authorize  investment in such Fund and to
reinvest any dividends or capital gains distributions.

MINIMUM INVESTMENT

There is a $250,000  initial  aggregate  investment  minimum  by each  Financial
Institution.  The Funds  may,  in their  discretion,  waive this  minimum  under
certain  circumstances but, in such event, the minimum must be reached within 90
days of opening the  account.  Financial  Institutions  who do not  maintain the
$250,000  minimum  will be given the option of  requesting  their  customers  to
exchange into Investor  Shares if the required  minimum  investment for Investor
Shares is met or having their customers' Shares redeemed.

NET ASSET VALUE

The net asset  value  ("NAV")  of the Shares is  determined  at the close of the
regular trading session of the New York Stock Exchange  (normally 4:00 p.m., New
York time) each day that both the Exchange and the New York Federal Reserve Bank
are open.  NAV per  share is  determined  by  dividing  the  total  value of the
securities  and other assets,  less  liabilities,  by the total number of Shares
outstanding.  Portfolio securities are valued at their amortized cost. Amortized
cost  valuation  involves  valuing  an  instrument  at its cost  and  thereafter
assuming a constant amortization to maturity (or such other date as permitted by
Rule 2a-7) of any discount or premium.  If fluctuating  interest rates cause the
market  value of a  portfolio  to  deviate  more  than 1/2 of 1% from the  value
determined on the basis of amortized  cost,  the Trustees will consider  whether
any  action,  such as  adjusting  the  Share's  NAV to  reflect  current  market
conditions,  should be  initiated  to prevent any  material  dilutive  effect on
shareholders.

SHARE CERTIFICATES

Share  certificates  are not  available  for the Shares in order to maintain the
general  liquidity  that is  representative  of a money  market fund and to help
facilitate transactions in shareholder accounts.

REDEMPTIONS

Redemptions,  like  purchases,  may be effected  only  through  the  accounts of
participating  Financial  Institutions.  Your Financial Institution will provide
you with instructions on redeeming shares.

Shares  of any  Fund  may be  redeemed  on any  business  day.  Redemptions  are
processed  at the NAV  next  calculated  after  receipt  and  acceptance  of the
redemption order by the Fund.  Redemption proceeds will normally be wired to the
participating  Financial  Institution the business day following  receipt of the
redemption  order,  but in no event later than seven days after  receipt of such
order.

SHAREHOLDER COMMUNICATIONS

Shareholders will receive annual and semiannual  reports including the financial
statements  of the Funds that they have  authorized  for  investment  from their
Financial Institution.  Each report will show the investments owned by each Fund
and the market values thereof,  as well as other information about the Funds and
their operations. The Trust's fiscal year ends October 31.

INVESTMENT POLICIES AND RESTRICTIONS

INVESTMENT OBJECTIVES

     As discussed in the Prospectus,  the investment  objective of each of Janus
Money  Market Fund and Janus  Government  Money  Market Fund is to seek  maximum
current  income  to  the  extent  consistent  with  stability  of  capital.  The
investment  objective of Janus  Tax-Exempt  Money Market Fund is to seek maximum
current income that is exempt from federal income taxes to the extent consistent
with  stability of capital.  There can be no assurance  that a Fund will achieve
its  investment  objective  or  maintain a stable  net asset  value of $1.00 per
share.  The investment  objectives of the Funds are not  fundamental  and may be
changed  by the  Trustees  of the Trust  (the  "Trustees")  without  shareholder
approval.

INVESTMENT RESTRICTIONS APPLICABLE TO ALL FUNDS

     As indicated in the Prospectus,  each Fund has adopted certain  fundamental
investment  restrictions  that cannot be changed without  shareholder  approval.
Shareholder  approval  means  approval by the lesser of (i) more than 50% of the
outstanding  voting  securities of the Trust (or a particular Fund or particular
class of Shares if a matter affects just that Fund or that class of Shares),  or
(ii) 67% or more of the voting securities present at a meeting if the holders of
more than 50% of the outstanding voting securities of the Trust (or a particular
Fund or class of Shares) are present or represented by proxy.

     As used in the  restrictions  set forth below and as used elsewhere in this
SAI, the term "U.S.  Government  Securities" shall have the meaning set forth in
the  Investment  Company Act of 1940, as amended (the "1940 Act").  The 1940 Act
defines U.S.  Government  Securities as  securities  issued or guaranteed by the
United States government,  its agencies or  instrumentalities.  U.S.  Government
Securities may also include repurchase  agreements  collateralized and municipal
securities escrowed with or refunded with escrowed U.S. government securities.

     The Funds have adopted the following fundamental policies:

     (1) With  respect to 75% of its assets,  a Fund may not purchase a security
other  than a U.S.  Government  Security,  if, as a result,  more than 5% of the
Fund's total assets would be invested in the  securities  of a single  issuer or
the Fund would own more than 10% of the  outstanding  voting  securities  of any
single issuer. (As noted in the Prospectus, the Funds are also currently subject
to  the  greater   diversification   standards  of  Rule  2a-7,  which  are  not
fundamental.)

   
     (2) A Fund may not  purchase  securities  if 25% or more of the  value of a
Fund's total assets would be invested in the  securities  of issuers  conducting
their  principal  business  activities in the same industry;  provided that: (i)
there is no limit on investments in U.S. Government Securities or in obligations
of domestic  commercial banks (including U.S.  branches of foreign banks subject
to regulations  under U.S. laws  applicable to domestic banks and, to the extent
that its parent is unconditionally  liable for the obligation,  foreign branches
of U.S. banks);  (ii) this limitation shall not apply to a Fund's investments in
municipal  securities;  (iii)  there  is no  limit  on  investments  in  issuers
domiciled in a single country;  (iv) financial  service companies are classified
according to the end users of their services (for example,  automobile  finance,
bank  finance  and  diversified  finance  are each  considered  to be a separate
industry);  and (v) utility companies are classified according to their services
(for example, gas, gas transmission, electric, and telephone are each considered
to be a separate industry).
    

     (3) A Fund may not act as an  underwriter  of securities  issued by others,
except to the extent that a Fund may be deemed an underwriter in connection with
the disposition of portfolio securities of such Fund.

     (4) A Fund may not lend  any  security  or make  any  other  loan if,  as a
result,  more than 25% of a Fund's total  assets would be lent to other  parties
(but this  limitation  does not apply to purchases  of  commercial  paper,  debt
securities or repurchase agreements).

     (5) A Fund may not  purchase or sell real estate or any  interest  therein,
except  that the Fund may invest in debt  obligations  secured by real estate or
interests  therein or securities  issued by companies that invest in real estate
or interests therein.

     (6) A Fund may borrow money for  temporary or emergency  purposes  (not for
leveraging)  in an amount  not  exceeding  25% of the value of its total  assets
(including the amount borrowed) less  liabilities  (other than  borrowings).  If
borrowings  exceed  25% of the  value of a Fund's  total  assets  by reason of a
decline in net assets, the Fund will reduce its borrowings within three business
days  to the  extent  necessary  to  comply  with  the 25%  limitation.  Reverse
repurchase  agreements  or the  segregation  of assets in  connection  with such
agreements shall not be considered borrowing for the purposes of this limit.

     (7)  Each  Fund  may,   notwithstanding  any  other  investment  policy  or
restriction  (whether  or not  fundamental),  invest  all of its  assets  in the
securities of a single open-end management investment company with substantially
the same fundamental  investment  objectives,  policies and restrictions as that
Fund.

     Each Fund has adopted the following nonfundamental  investment restrictions
that may be changed by the Trustees without shareholder approval:

                                       3
<PAGE>
     (1) A Fund may not invest in securities or enter into repurchase agreements
with respect to any securities if, as a result,  more than 10% of the Fund's net
assets would be invested in  repurchase  agreements  not entitling the holder to
payment of  principal  within  seven days and in other  securities  that are not
readily  marketable  ("illiquid  investments").  The  Trustees,  or  the  Fund's
investment adviser acting pursuant to authority  delegated by the Trustees,  may
determine that a readily available market exists for certain  securities such as
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, or any successor to such rule, Section 4(2) commercial paper and municipal
lease  obligations.  Accordingly,  such  securities  may not be  subject  to the
foregoing limitation.

     (2) A Fund may not invest in the securities of another investment  company,
except to the extent permitted by the 1940 Act.

     (3) A Fund may not purchase  securities  on margin,  or make short sales of
securities,  except for short sales  against  the box and the use of  short-term
credit  necessary  for  the  clearance  of  purchases  and  sales  of  portfolio
securities.

     (4) A Fund may not invest more than 5% of the value of its total  assets in
the securities of any issuer that has conducted  continuous  operations for less
than three years,  including operations of predecessors,  except that this shall
not affect the Fund's  ability to invest in U.S.  Government  Securities,  fully
collateralized  debt  obligations,  municipal  obligations,  securities that are
rated by at least one nationally recognized  statistical rating organization and
securities  guaranteed  as to  principal  and  interest  by an  issuer  in whose
securities the Fund could invest.

     (5) A Fund may not pledge,  mortgage,  hypothecate  or encumber  any of its
assets except to secure  permitted  borrowings or in connection  with  permitted
short sales.

     (6) A Fund may not invest directly in interests in oil and gas or interests
in other mineral  exploration or development  programs or leases;  however,  the
Fund may own debt securities of companies engaged in those businesses.

     (7) A Fund may not  invest  in  companies  for the  purpose  of  exercising
control of management.

     For  purposes  of the  Funds'  restriction  on  investing  in a  particular
industry, the Funds will rely primarily on industry classifications as published
by Bloomberg L.P.,  subject to the exceptions  noted in fundamental  restriction
number two above. To the extent that such  classifications are so broad that the
primary economic characteristics in a single class are materially different, the
Funds may further classify  issuers in accordance with industry  classifications
as published by the Securities and Exchange Commission.

TYPES OF SECURITIES AND INVESTMENT TECHNIQUES

     Each of the Funds may invest only in  "eligible  securities"  as defined in
Rule 2a-7  adopted  under the 1940 Act.  Generally,  an  eligible  security is a
security that (i) is denominated in U.S. dollars and has a remaining maturity of
397 days or less (as  calculated  pursuant to Rule 2a-7);  (ii) is rated,  or is
issued by an issuer with  short-term debt  outstanding  that is rated, in one of
the two highest rating categories by any two nationally  recognized  statistical
rating  organizations  ("NRSROs") or, if only one NRSRO has issued a rating,  by
that NRSRO (the "Requisite NRSROs") or is unrated and of comparable quality to a
rated security, as determined by Janus Capital; and (iii) has been determined by
Janus Capital to present minimal credit risks pursuant to procedures approved by
the Trustees.  In addition,  the Funds will maintain a  dollar-weighted  average
portfolio  maturity  of 90 days or less.  A  description  of the ratings of some
NRSROs appears in Appendix A.

   
     Under Rule 2a-7,  a Fund may not invest more than five percent of its total
assets  in  the  securities  of  any  one  issuer  other  than  U.S.  Government
Securities, provided that in certain cases a Fund may invest more than 5% of its
assets in a single  issuer  for a period  of up to three  business  days.  Until
pending amendments to Rule 2a-7 become effective,  up to 25% of Janus Tax-Exempt
Money  Market  Fund's  assets may be invested  without  regard to the  foregoing
limitations.
    

     Pursuant to Rule 2a-7,  each Fund  (except  Janus  Tax-Exempt  Money Market
Fund) will invest at least 95% of its total assets in  "first-tier"  securities.
First-tier  securities are eligible  securities that are rated, or are issued by
an issuer with short-term debt  outstanding that is rated, in the highest rating
category by the Requisite  NRSROs or are unrated and of comparable  quality to a
rated security. In addition, a Fund may invest in "second-tier" securities which
are eligible  securities  that are not first-tier  securities.  However,  a Fund
(except for Janus Tax-Exempt Money Market Fund, in certain cases) may not invest
in a second-tier  security if immediately after the acquisition thereof the Fund
would have invested more than (i) the greater of one percent of its total assets
or one million dollars in second-tier  securities issued by that issuer, or (ii)
five percent of its total assets in second-tier securities.

     The  following  discussion  of types of  securities  in which the Funds may
invest supplements and should be read in conjunction with the Prospectus.

                                       4
<PAGE>
PARTICIPATION INTERESTS

     Each Fund may purchase  participation  interests in loans or  securities in
which the Funds may  invest  directly.  Participation  interests  are  generally
sponsored or issued by banks or other  financial  institutions.  A participation
interest  gives  a Fund  an  undivided  interest  in  the  underlying  loans  or
securities  in the  proportion  that the  Fund's  interest  bears  to the  total
principal amount of the underlying loans or securities. Participation interests,
which may have fixed,  floating or variable  rates,  may carry a demand  feature
backed by a letter of credit or  guarantee of a bank or  institution  permitting
the holder to tender  them back to the bank or other  institution.  For  certain
participation  interests,  a Fund will have the right to demand payment,  on not
more than seven  days'  notice,  for all or a part of the  Fund's  participation
interest.  The Funds  intend to  exercise  any demand  rights they may have upon
default  under the terms of the loan or  security,  to provide  liquidity  or to
maintain or improve the quality of the Funds' investment portfolio.  A Fund will
only purchase  participation  interests  that Janus Capital  determines  present
minimal credit risks.

VARIABLE AND FLOATING RATE NOTES

     Janus Money Market Fund also may purchase variable and floating rate demand
notes of  corporations  and  other  entities,  which are  unsecured  obligations
redeemable upon not more than 30 days' notice.  These obligations include master
demand notes that permit  investment of fluctuating  amounts at varying rates of
interest pursuant to direct arrangements with the issuer of the instrument.  The
issuer of these obligations often has the right, after a given period, to prepay
the outstanding  principal  amount of the obligations upon a specified number of
days' notice. These obligations generally are not traded, nor generally is there
an established  secondary market for these  obligations.  To the extent a demand
note does not have a seven day or shorter demand feature and there is no readily
available market for the obligation, it is treated as an illiquid investment.

MORTGAGE- AND ASSET-BACKED SECURITIES

     The Funds may invest in  mortgage-backed  securities,  which  represent  an
interest  in a pool of  mortgages  made by  lenders  such as  commercial  banks,
savings and loan  institutions,  mortgage bankers,  mortgage brokers and savings
banks.   Mortgage-backed   securities   may  be   issued  by   governmental   or
government-related  entities  or by  non-governmental  entities  such as  banks,
savings and loan institutions,  private mortgage insurance  companies,  mortgage
bankers and other secondary market issuers.

     Interests in pools of mortgage-backed securities differ from other forms of
debt securities which normally provide for periodic payment of interest in fixed
amounts  with  principal  payments  at  maturity or  specified  call  dates.  In
contrast,  mortgage-backed securities provide periodic payments which consist of
interest  and,  in most  cases,  principal.  In  effect,  these  payments  are a
"pass-through"  of the periodic  payments and optional  prepayments  made by the
individual borrowers on their mortgage loans, net of any fees paid to the issuer
or   guarantor   of  such   securities.   Additional   payments  to  holders  of
mortgage-backed  securities are caused by prepayments resulting from the sale of
the underlying residential property,  refinancing or foreclosure, net of fees or
costs which may be incurred.

     As prepayment rates of individual  pools of mortgage loans vary widely,  it
is not possible to predict accurately the average life of a particular security.
Although  mortgage-backed  securities are issued with stated maturities of up to
forty years,  unscheduled  or early  payments of  principal  and interest on the
underlying  mortgages  may  shorten   considerably  the  effective   maturities.
Mortgage-backed  securities may have varying  assumptions  for average life. The
volume  of  prepayments  of  principal  on a  pool  of  mortgages  underlying  a
particular security will influence the yield of that security, and the principal
returned to a Fund may be reinvested in instruments whose yield may be higher or
lower than that which might have been obtained had the prepayments not occurred.
When interest rates are declining, prepayments usually increase, with the result
that reinvestment of principal prepayments will be at a lower rate than the rate
applicable to the original mortgage-backed security.

     The  Funds may  invest in  mortgage-backed  securities  that are  issued by
agencies or instrumentalities  of the U.S.  government.  The Government National
Mortgage  Association  ("GNMA") is the principal federal government guarantor of
mortgage-backed  securities.  GNMA is a wholly-owned U.S. government corporation
within the Department of Housing and Urban  Development.  GNMA  Certificates are
debt  securities  which  represent  an  interest  in one  mortgage  or a pool of
mortgages which are insured by the Federal Housing Administration or the Farmers
Home Administration or are guaranteed by the Veterans Administration.  The Funds
may  also  invest  in  pools of  conventional  mortgages  which  are  issued  or
guaranteed by agencies of the U.S. government.  GNMA pass-through securities are
considered  to be riskless  with  respect to default in that (i) the  underlying
mortgage loan  portfolio is comprised  entirely of  government-backed  loans and
(ii) the timely  payment of both  principal  and interest on the  securities  is
guaranteed  by the full faith and credit of the U.S.  government,  regardless of
whether  or not  payments  have  been  made on the  underlying  mortgages.  GNMA
pass-through  securities  are,  however,  subject  to the  same  market  risk as
comparable  debt  securities.  Therefore,  the  market  value of a  Fund's  GNMA
securities  can be expected to  fluctuate  in response to changes in  prevailing
interest rate levels.

     Residential  mortgage  loans  are  pooled  also by the  Federal  Home  Loan
Mortgage Corporation ("FHLMC"). FHLMC is a privately managed, publicly chartered
agency   created  by  Congress  in  1970  for  the  purpose  of  increasing  the
availability  of  mortgage  credit  for   residential   housing.   FHLMC  issues
participation  certificates  ("PCs") which represent interests in mortgages from
FHLMC's

                                       5
<PAGE>
national  portfolio.  The  mortgage  loans  in  FHLMC's  portfolio  are not U.S.
government  backed;  rather,  the loans are either uninsured with  loan-to-value
ratios of 80% or less, or privately insured if the  loan-to-value  ratio exceeds
80%. FHLMC guarantees the timely payment of interest and ultimate  collection of
principal on FHLMC PCs; the U.S.  government  does not  guarantee  any aspect of
FHLMC PCs.

     The    Federal    National    Mortgage    Association    ("FNMA")    is   a
government-sponsored  corporation owned entirely by private shareholders.  It is
subject to general regulation by the Secretary of Housing and Urban Development.
FNMA purchases  residential  mortgages from a list of approved  seller/servicers
which include savings and loan  associations,  savings banks,  commercial banks,
credit  unions and  mortgage  bankers.  FNMA  guarantees  the timely  payment of
principal and interest on the pass-through  securities  issued by FNMA; the U.S.
government does not guarantee any aspect of the FNMA pass-through securities.

     The Funds may also invest in privately-issued mortgage-backed securities to
the  extent   permitted  by  their  investment   restrictions.   Mortgage-backed
securities offered by private issuers include pass-through  securities comprised
of pools of conventional residential mortgage loans; mortgage-backed bonds which
are considered to be debt  obligations of the institution  issuing the bonds and
which  are  collateralized  by  mortgage  loans;  and  collateralized   mortgage
obligations  ("CMOs") which are  collateralized  by  mortgage-backed  securities
issued by GNMA, FHLMC or FNMA or by pools of conventional mortgages.

     Asset-backed  securities represent direct or indirect  participation in, or
are secured by and payable from, assets other than  mortgage-backed  assets such
as motor vehicle installment sales contracts, installment loan contracts, leases
of various types of real and personal  property and  receivables  from revolving
credit   agreements   (credit   cards).   Asset-backed   securities  have  yield
characteristics similar to those of mortgage-backed securities and, accordingly,
are subject to many of the same risks.

REVERSE REPURCHASE AGREEMENTS

     Reverse  repurchase  agreements  are  transactions  in which a Fund sells a
security and  simultaneously  commits to repurchase that security from the buyer
at an agreed  upon price on an agreed upon future  date.  The resale  price in a
reverse  repurchase  agreement  reflects a market rate of  interest  that is not
related to the coupon rate or maturity of the sold security.  For certain demand
agreements,  there is no agreed upon repurchase  date and interest  payments are
calculated daily, often based upon the prevailing overnight repurchase rate. The
Funds will use the  proceeds of reverse  repurchase  agreements  only to satisfy
unusually heavy redemption requests or for other temporary or emergency purposes
without the  necessity of selling  portfolio  securities  or to earn  additional
income on portfolio securities.

     Generally,  a reverse repurchase  agreement enables the Fund to recover for
the term of the reverse repurchase agreement all or most of the cash invested in
the portfolio  securities sold and to keep the interest  income  associated with
those  portfolio  securities.  Such  transactions  are only  advantageous if the
interest cost to the Fund of the reverse repurchase transaction is less than the
cost of obtaining the cash otherwise.  In addition,  interest costs on the money
received in a reverse repurchase agreement may exceed the return received on the
investments made by a Fund with those monies.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

     Each Fund may purchase  securities  on a  when-issued  or delayed  delivery
basis. A Fund will enter into such  transactions  only when it has the intention
of actually  acquiring the  securities.  To facilitate  such  acquisitions,  the
Funds'  custodian will segregate cash or high quality liquid assets in an amount
at least equal to such commitments. On delivery dates for such transactions, the
Fund  will  meet  its  obligations  from  maturities,  sales  of the  segregated
securities or from other available sources of cash. If a Fund chooses to dispose
of the right to acquire a  when-issued  security  prior to its  acquisition,  it
could, as with the disposition of any other portfolio  obligation,  incur a gain
or loss due to market  fluctuation.  At the time a Fund makes the  commitment to
purchase  securities on a when-issued or delayed  delivery basis, it will record
the  transaction  as a  purchase  and  thereafter  reflect  the  value  of  such
securities in determining its net asset value.

MUNICIPAL LEASES

     Janus Money Market Fund and Janus  Tax-Exempt  Money Market Fund may invest
in municipal leases. Municipal leases frequently have special risks not normally
associated  with general  obligation or revenue  bonds.  Leases and  installment
purchase or conditional  sale contracts (which normally provide for title to the
leased  asset to pass  eventually  to the  government  issuer) have evolved as a
means for governmental issuers to acquire property and equipment without meeting
the  constitutional  and statutory  requirements  for the issuance of debt.  The
debt-issuance limitations of many state constitutions and statutes are deemed to
be  inapplicable  because  of the  inclusion  in many  leases  or  contracts  of
"non-appropriation"  clauses that provide  that the  governmental  issuer has no
obligation to make future  payments under the lease or contract  unless money is
appropriated for such purpose by the appropriate legislative body on a yearly or
other periodic  basis. A Fund will only purchase  municipal  leases subject to a
non-appropriation  clause when the payment of principal and accrued  interest is
backed by an unconditional  irrevocable letter of credit, or guarantee of a bank
or other  entity  that meets the  criteria  described  in the  Prospectus  under
"Taxable Investments."

                                       6

     In evaluating municipal lease obligations, Janus Capital will consider such
factors  as it deems  appropriate,  including:  (a)  whether  the  lease  can be
canceled;  (b) the  ability  of the  lease  obligee  to  direct  the sale of the
underlying assets; (c) the general  creditworthiness  of the lease obligor;  (d)
the likelihood that the municipality will discontinue  appropriating funding for
the leased property in the event such property is no longer considered essential
by the municipality; (e) the legal recourse of the lease obligee in the event of
such a failure to appropriate  funding;  (f) whether the security is backed by a
credit enhancement such as insurance;  and (g) any limitations which are imposed
on the lease obligor's ability to utilize substitute  property or services other
than  those  covered  by the  lease  obligation.  If a  lease  is  backed  by an
unconditional letter of credit or other unconditional  credit enhancement,  then
Janus Capital may determine that a lease is an eligible  security  solely on the
basis of its evaluation of the credit enhancement.

     Municipal leases, like other municipal debt obligations, are subject to the
risk of non-payment.  The ability of issuers of municipal  leases to make timely
lease payments may be adversely  impacted in general  economic  downturns and as
relative  governmental cost burdens are allocated and reallocated among federal,
state and local governmental units. Such non-payment would result in a reduction
of income to the  Funds,  and could  result in a  reduction  in the value of the
municipal lease  experiencing  non-payment  and a potential  decrease in the net
asset value of a Fund.

PERFORMANCE DATA

     A Fund may  provide  current  annualized  and  effective  annualized  yield
quotations based on its daily dividends.  These quotations may from time to time
be used in  advertisements,  shareholder  reports  or  other  communications  to
shareholders.  All performance  information supplied by the Funds in advertising
is historical and is not intended to indicate future returns.

     In performance advertising, the Funds may compare their Shares' performance
information  with data published by independent  evaluators such as Morningstar,
Inc.,  Lipper Analytical  Services,  Inc., or  CDC/Wiesenberger,  IBC/Donoghue's
Money Fund Report or other companies  which track the investment  performance of
investment  companies  ("Fund Tracking  Companies").  The Funds may also compare
their Shares' performance  information with the performance of recognized stock,
bond and other  indices,  including but not limited to the Municipal Bond Buyers
Indices,  the Salomon Brothers Bond Index, the Lehman Bond Index, the Standard &
Poor's 500 Composite Stock Price Index, the Dow Jones Industrial  Average,  U.S.
Treasury  bonds,  bills or notes and  changes  in the  Consumer  Price  Index as
published by the U.S.  Department  of  Commerce.  The Funds may refer to general
market  performance  over past time periods such as those  published by Ibbotson
Associates (for instance,  its "Stocks,  Bonds, Bills and Inflation  Yearbook").
The Funds may also refer in such materials to mutual fund  performance  rankings
and other data published by Fund Tracking Companies. Performance advertising may
also refer to  discussions  of the Funds and  comparative  mutual  fund data and
ratings  reported in independent  periodicals,  such as newspapers and financial
magazines. The Funds may also compare the Shares' yield to those of certain U.S.
Treasury obligations or other money market instruments.

     Any current yield quotation of the Shares which is used in such a manner as
to be subject to the provisions of Rule 482(d) under the Securities Act of 1933,
as amended, shall consist of an annualized historical yield, carried at least to
the nearest  hundredth of one percent,  based on a specific  seven  calendar day
period.  Current  yield shall be calculated  by (a)  determining  the net change
during a seven calendar day period in the value of a hypothetical account having
a balance of one Share at the  beginning  of the period,  (b)  dividing  the net
change by the value of the  account at the  beginning  of the period to obtain a
base  period  return,   and  (c)   multiplying  the  quotient  by  365/7  (i.e.,
annualizing). For this purpose, the net change in account value will reflect the
value of additional  Shares  purchased with  dividends  declared on the original
Share and dividends  declared on both the original Share and any such additional
Shares,  but will not  reflect  any  realized  gains or losses  from the sale of
securities  or  any  unrealized   appreciation   or  depreciation  on  portfolio
securities.  In addition,  the Shares may advertise  effective yield quotations.
Effective yield quotations are calculated by adding 1 to the base period return,
raising the sum to a power  equal to 365/7,  and  subtracting  1 from the result
(i.e., compounding).

     Janus  Tax-Exempt  Money Market Fund's tax equivalent  yield is the rate an
investor  would have to earn from a fully  taxable  investment in order to equal
such Shares' yield after taxes. Tax equivalent yields are calculated by dividing
Janus  Tax-Exempt  Money Market Fund's yield by one minus the stated  federal or
combined  federal and state tax rate.  If only a portion of the Shares' yield is
tax-exempt, only that portion is adjusted in the calculation.

</TABLE>
*Janus  Tax-Exempt  Money  Market  Fund tax  equivalent  yield for the seven day
period ended  October 31, 1996 was 4.51% for the  Investor  Shares and 5.14% for
the Institutional Shares.
    

     Although  published yield information is useful to investors in reviewing a
Fund's  performance,  investors should be aware that the Fund's yield fluctuates
from  day to day and  that the  Fund's  yield  for any  given  period  is not an
indication or  representation by the Fund of future yields or rates of return on
the Shares. Also, Financial  Institutions may charge their customers direct fees
in  connection  with an  investment  in a Fund,  which  will have the  effect of
reducing  the  Fund's net yield to those  shareholders.  The yield on a class of
Shares  is not  fixed or  guaranteed,  and an  investment  in the  Shares is not
insured.  Accordingly,  yield information may not necessarily be used to compare
Shares with investment alternatives which, like money market instruments or bank
accounts, may provide a fixed rate of interest. In addition, because investments
in the  Funds  are not  insured  or  guaranteed,  yield  on the  Shares  may not
necessarily be used to compare the Shares with investment alternatives which are
insured or guaranteed.

DETERMINATION OF NET ASSET VALUE

     Pursuant  to the  rules of the  Securities  and  Exchange  Commission,  the
Trustees have established procedures to stabilize each Fund's net asset value at
$1.00  per  Share.  These  procedures  include  a review  of the  extent  of any
deviation  of net asset  value per  Share as a result  of  fluctuating  interest
rates,  based on available  market rates,  from the Fund's $1.00  amortized cost
price per Share.  Should  that  deviation  exceed 1/2 of 1%, the  Trustees  will
consider  whether any action should be initiated to eliminate or reduce material
dilution  or other  unfair  results to  shareholders.  Such  action may  include
redemption of Shares in kind,  selling  portfolio  securities prior to maturity,
reducing or  withholding  dividends and utilizing a net asset value per Share as
determined by using available  market  quotations.  Each Fund i) will maintain a
dollar-weighted  average  portfolio  maturity  of 90 days or less;  ii) will not
purchase  any  instrument  with a remaining  maturity  greater  than 397 days or
subject to a  repurchase  agreement  having a duration of greater than 397 days;
iii) will limit portfolio investments, including repurchase agreements, to those
U.S.  dollar-denominated  instruments that Janus Capital has determined  present
minimal credit risks pursuant to procedures established by the Trustees; and iv)
will comply with certain reporting and recordkeeping  procedures.  The Trust has
also established  procedures to ensure that portfolio securities meet the Funds'
high quality criteria.

INVESTMENT ADVISER AND ADMINISTRATOR

     As stated in the Prospectus, each Fund has an Investment Advisory Agreement
with Janus Capital,  100 Fillmore  Street,  Denver,  Colorado  80206-4923.  Each
Advisory  Agreement  provides that Janus Capital will furnish  continuous advice
and  recommendations  concerning  the  Funds'  investments.  The Funds have each
agreed to  compensate  Janus  Capital for its  advisory  services by the monthly
payment of an advisory  fee at the annual rate of .20% of the average  daily net
assets of each  Fund.  However,  Janus  Capital  has agreed to waive .10% of the
value of each Fund's average daily net assets of the advisory fee. Janus Capital
may  modify or  terminate  the  waiver  at any time upon 90 days'  notice to the
Trustees. In addition, the Funds pay brokerage commissions or dealer spreads and
other expenses in connection with the execution of portfolio transactions.

     The following table  summarizes the advisory fees paid by the Funds for the
fiscal years ended October 31:

     On  behalf  of the  Shares,  each of the  Funds  has also  entered  into an
Administration   Agreement   with  Janus   Capital.   Under  the  terms  of  the
Administration  Agreements,  each of the Funds has  agreed to  compensate  Janus
Capital for  administrative  services at the annual rate of .40% of the value of
the  average  daily net  assets of the Shares for  certain  services,  including
custody, transfer agent fees and expenses, legal fees not related to litigation,
accounting  expenses,   net  asset  value  determination  and  fund  accounting,
recordkeeping,  and blue sky registration and monitoring services,  registration
fees, expenses of shareholders'  meetings and reports to shareholders,  costs of
preparing,  printing  and mailing the Shares'  Prospectuses  and  Statements  of
Additional  Information  to current  shareholders,  and other costs of complying
with  applicable  laws  regulating the sale of Shares.  Each Fund will pay those
expenses not assumed by Janus Capital,  including  interest and taxes,  fees and
expenses of Trustees who are not affiliated  with Janus Capital,  audit fees and
expenses,  and extraordinary  costs. Janus Capital has agreed to waive a portion
of the  administration  fee, and  accordingly the effective rate for calculating
the administration fee payable by the Shares will be .30% for that period. Janus
Capital  may  terminate  the  waiver  at any time  upon 90 days'  notice  to the
Trustees.

     Janus  Capital  may  use  all or a  portion  of its  administration  fee to
compensate Financial Institutions for providing administrative services to their
customers  who invest in the Shares.  The types of services  that the  Financial
Institutions  would provide include  serving as the sole  shareholder of record,
shareholder  recordkeeping,  processing and aggregating  purchase and redemption
transactions,  providing periodic statements, forwarding shareholder reports and
other materials,  and providing other similar services that the Funds would have
to perform if they were dealing directly with the beneficial owners, rather than
the Financial Institutions, as shareholders of record.

     The Advisory  Agreements for each Fund became effective on December 9, 1994
and will  continue in effect until June 16, 1997,  and  thereafter  from year to
year so long as such  continuance  is  approved  annually  by a majority  of the
Trustees who are not parties to the Advisory Agreements or interested persons of
any such party, and by either a majority of the Funds' outstanding voting shares
or the  Trustees.  Each  Advisory  Agreement  i) may be  terminated  without the
payment of any penalty by any Fund or Janus Capital on 60 days' written  notice;
ii) terminates automatically in the event of its assignment; and iii) generally,
may not be amended  without the  approval  of a majority of the  Trustees of the
affected  Fund,  including the Trustees who are not  interested  persons of that
Fund or Janus Capital and, to the extent required by the 1940 Act, the vote of a
majority of the outstanding voting securities of that Fund.

     Janus Capital also performs  investment  advisory services for other mutual
funds,  and for  individual,  charitable,  corporate  and  retirement  accounts.
Investment  decisions for each account  managed by Janus Capital,  including the
Funds, are made independently from those for any other account that is or may in
the future become managed by Janus Capital or its  affiliates.  If,  however,  a
number of accounts managed by Janus Capital are contemporaneously engaged in the
purchase or sale of the same security,  the orders may be aggregated  and/or the
transactions  may be  averaged  as to  price  and  allocated  equitably  to each
account.  In some cases,  this policy might  adversely  affect the price paid or
received by an account or the size of the position obtained or liquidated for an
account.  Pursuant to an exemptive order granted by the SEC, the Funds and other
funds advised by Janus Capital may also transfer daily  uninvested cash balances
into one or more joint trading  accounts.  Assets in the joint trading  accounts
are invested in money market  instruments  and the proceeds are allocated to the
participating funds on a pro rata basis.

     Each account managed by Janus Capital has its own investment  objective and
is managed in accordance with that objective by a particular  portfolio  manager
or team of  portfolio  managers.  As a  result,  from  time to time  two or more
different  managed  accounts may pursue  divergent  investment  strategies  with
respect to investments or categories of investments.

   
     As indicated in the  Prospectus,  Janus  Capital does not permit  portfolio
managers to purchase and sell securities for their own accounts except under the
limited  exceptions  contained  in Janus  Capital's  policy  regarding  personal
investing by  directors,  officers and employees of Janus Capital and the Funds.
The policy requires investment  personnel and officers of Janus Capital,  inside
directors of Janus Capital and the Funds and other designated  persons deemed to
have access to current  trading  information  to pre-clear all  transactions  in
securities not otherwise exempt under the policy. Requests for trading authority
will be denied when,  among other  reasons,  the proposed  personal  transaction
would be  contrary  to the  provisions  of the  policy  or would  be  deemed  to
adversely affect any transaction then known to be under  consideration for or to
have been effected on behalf of any client account, including the Funds.
    

     In addition to the  pre-clearance  requirement  described above, the policy
subjects investment personnel, officers and directors/ Trustees of Janus Capital
and the Funds to various trading  restrictions  and reporting  obligations.  All
reportable transactions are reviewed for compliance with Janus Capital's policy.
Those persons also may be required under certain  circumstances to forfeit their
profits made from personal trading.

     The provisions of the policy are  administered by and subject to exceptions
authorized by Janus Capital.

     Kansas City Southern  Industries,  Inc., a publicly  traded holding company
whose primary subsidiaries are engaged in transportation, information processing
and financial services ("KCSI"), owns approximately 83% of Janus Capital. Thomas
H.  Bailey,  the  President  and  Chairman of the Board of Janus  Capital,  owns
approximately  12% of its voting  stock and, by agreement  with KCSI,  selects a
majority of Janus Capital's Board.

CUSTODIAN, TRANSFER AGENT AND CERTAIN AFFILIATIONS

     United  Missouri  Bank,  N.A.,  P.O.  Box  419226,  Kansas  City,  Missouri
64141-6226,  is the Funds'  custodian.  The custodian holds the Funds' assets in
safekeeping  and  collects  and  remits  the  income  thereon,  subject  to  the
instructions of each Fund.

     Janus  Service  Corporation  ("Janus  Service"),  P.O. Box 173375,  Denver,
Colorado 80217-3375,  a wholly-owned  subsidiary of Janus Capital, is the Funds'
transfer   agent.   In  addition,   Janus   Service   provides   certain   other
administrative,  recordkeeping and shareholder  relations services to the Funds.
The Funds do not pay Janus Service a fee.

     Janus  Distributors,  Inc.  ("Janus  Distributors"),  100 Fillmore  Street,
Denver,  Colorado  80206,  a  wholly-owned  subsidiary  of Janus  Capital,  is a
distributor of the Funds.  Janus  Distributors  is registered as a broker-dealer
under the Securities  Exchange Act of 1934 (the "Exchange  Act") and is a member
of the National Association of Securities Dealers,  Inc. Janus Distributors acts
as the agent of the  Funds in  connection  with the sale of their  shares in all
states in which the shares are  registered  and in which Janus  Distributors  is
qualified  as  a  broker-dealer.   Under  the  Distribution   Agreement,   Janus
Distributors  continuously  offers the Funds'  shares and accepts  orders at net
asset value.  No sales  charges are paid by investors.  Promotional  expenses in
connection with offers and sales of shares are paid by Janus Capital.

     Janus  Capital also may make  payments to selected  broker-dealer  firms or
institutions  which were instrumental in the acquisition of shareholders for the
Funds or which  performed  services with respect to  shareholder  accounts.  The
minimum  aggregate  size required for  eligibility  for such  payments,  and the
factors in selecting the broker-dealer firms and institutions to which they will
be made, are determined from time to time by Janus Capital.

PORTFOLIO TRANSACTIONS AND BROKERAGE

     Decisions  as to the  assignment  of  portfolio  business for the Funds and
negotiation of its commission rates are made by Janus Capital whose policy is to
obtain the "best execution" (prompt and reliable execution at the most favorable
security price) of all portfolio transactions.

     In  selecting  brokers and dealers and in  negotiating  commissions,  Janus
Capital  considers a number of  factors,  including  but not  limited to:  Janus
Capital's knowledge of currently available negotiated commission rates or prices
of  securities  currently  available and other current  transaction  costs;  the
nature of the security being traded;  the size and type of the transaction;  the
nature and  character  of the markets for the  security to be purchased or sold;
the desired  timing of the trade;  the  activity  existing  and  expected in the
market  for  the  particular  security;  confidentiality;  the  quality  of  the
execution,  clearance and settlement services; financial stability of the broker
or dealer;  the  existence  of actual or  apparent  operational  problems of any
broker or dealer; and research products or services provided.  In recognition of
the  value  of  the  foregoing  factors,   Janus  Capital  may  place  portfolio
transactions  with a broker or dealer with whom it has  negotiated  a commission
that is in excess of the commission  another broker or dealer would have charged
for effecting that  transaction  if Janus Capital  determines in good faith that
such  amount  of  commission  was  reasonable  in  relation  to the value of the
brokerage  and  research  provided by such  broker or dealer  viewed in terms of
either that particular  transaction or of the overall  responsibilities of Janus
Capital.  These research and other services may include, but are not limited to,
general  economic and security  market  reviews,  industry and company  reviews,
evaluations  of  securities,  recommendations  as to the  purchase  and  sale of
securities  and access to third  party  publications,  computer  and  electronic
equipment   and  software.   Research   received  from  brokers  or  dealers  is
supplemental to Janus Capital's own research efforts.

     For the fiscal  year ended  October 31,  1996,  the Funds did not incur any
brokerage  commissions.  Brokerage  commissions are not normally  charged on the
purchase and sale of money market instruments.

     Janus  Capital may use research  products  and services in servicing  other
accounts in addition to the Funds. If Janus Capital determines that any research
product or service has a mixed use, such that it also serves  functions  that do
not assist in the investment decision-making process, Janus Capital may allocate
the costs of such  service  or  product  accordingly.  Only that  portion of the
product  or  service  that  Janus  Capital  determines  will  assist  it in  the
investment  decision-making  process  may be paid  for in  brokerage  commission
dollars. Such allocation may create a conflict of interest for Janus Capital.

     Janus  Capital  may  consider  sales of  Shares by a  broker-dealer  or the
recommendation  of a broker-dealer to its customers that they purchase Shares as
a  factor  in  the  selection  of   broker-dealers  to  execute  Fund  portfolio
transactions. Janus Capital may also consider payments made by brokers effecting
transactions  for a Fund i) to the Fund or ii) to other persons on behalf of the
Fund for  services  provided to the Fund for which it would be obligated to pay.
In placing portfolio business with such broker-dealers,  Janus Capital will seek
the best execution of each transaction.

     When the Funds purchase or sell a security in the over-the-counter  market,
the transaction takes place directly with a principal market-maker,  without the
use of a broker,  except in those  circumstances  where in the  opinion of Janus
Capital  better  prices and  executions  will be  achieved  through the use of a
broker.

objective, policies and techniques. The Trustees also supervise the operation of
the Funds by their officers and review the investment  decisions of the officers
although  they do not  actively  participate  on a regular  basis in making such
decisions.

     The Executive Committee of the Trustees shall have and may exercise all the
powers and  authority  of the Board except for matters  requiring  action by the
whole  Board   pursuant  to  the  Trust's   Bylaws  or   Declaration  of  Trust,
Massachusetts Law or the 1940 Act.

particularly for money market funds.

     The following table shows the aggregate  compensation  paid to each Trustee

Funds.

PURCHASE OF SHARES

     As stated in the  Prospectus,  Janus  Distributors  is a distributor of the
Funds' shares. Shares are sold at the net asset value per share as determined at
the close of the regular  trading  session of the New York Stock  Exchange  (the
"NYSE" or the "Exchange")  next occurring after a purchase order is received and
accepted by a Fund.  A Fund's net asset value is  calculated  each day that both
the NYSE and the New York  Federal  Reserve  Bank are  open.  As  stated  in the
Prospectus,  the Funds each seek to  maintain a stable net asset value per share
of $1.00. The  Shareholder's  Guide Section of the Prospectus  contains detailed
information about the purchase of Shares.

REDEMPTIONS OF SHARES

   
     Redemptions,  like  purchases,  may  only be  effected  through  the  trust
accounts,  cash management  programs and similar programs of participating banks
and financial institutions.  Shares normally will be redeemed for cash, although
each  Fund  retains
    

                                       12
<PAGE>
   
the right to redeem its shares in kind under unusual circumstances,  in order to
protect the  interests  of  remaining  shareholders,  by delivery of  securities
selected from its assets at its discretion.  However,  the Funds are governed by
Rule 18f-1 under the 1940 Act,  which requires each Fund to redeem shares solely
in cash up to the lesser of  $250,000  or 1% of the NAV of that Fund  during any
90-day period for any one  shareholder.  Should  redemptions by any  shareholder
exceed such  limitation,  a Fund will have the option of redeeming the excess in
cash or in kind.  If shares are  redeemed  in kind,  the  redeeming  shareholder
generally  will incur  brokerage  costs in  converting  the assets to cash.  The
method of valuing  securities used to make  redemptions in kind will be the same
as the method of valuing  portfolio  securities  described  under "Shares of the
Trust" and such valuation will be made as of the same time the redemption  price
is determined.
    

     The right to require  the Funds to redeem its shares may be  suspended,  or
the date of  payment  may be  postponed,  whenever  (1)  trading  on the NYSE is
restricted,  as determined by the SEC, or the NYSE is closed except for holidays
and  weekends,  (2) the SEC permits  such  suspension  and so orders,  or (3) an
emergency  exists as  determined  by the SEC so that  disposal of  securities or
determination of NAV is not reasonably practicable.

SHAREHOLDER ACCOUNTS

     Detailed  information about the general procedures for shareholder accounts
is set forth in the Prospectus. Applications to open accounts may be obtained by
calling or writing your Financial Institution.

DIVIDENDS AND TAX STATUS

     Dividends  representing  substantially all of the net investment income and
any net realized  gains on sales of securities  are declared  daily,  Saturdays,
Sundays and holidays included,  and distributed on the last business day of each
month. If a month begins on a Saturday,  Sunday or holiday,  dividends for those
days are declared at the end of the preceding month and distributed on the first
business day of the month. A shareholder may receive dividends via wire transfer
or may choose to have dividends automatically  reinvested in a Fund's Shares. As
described in the  Prospectus,  Shares  purchased by wire on a bank  business day
will receive that day's dividend if the purchase is effected at or prior to 3:00
p.m.  (New York time) for Janus  Money  Market Fund and Janus  Government  Money
Market Fund and 12:00 p.m.  (New York time) for Janus  Tax-Exempt  Money  Market
Fund.  Otherwise,  such Shares will begin to accrue  dividends on the first bank
business day following  receipt of the order.  Requests for redemption of Shares
will be redeemed at the next  determined  net asset value.  Redemption  requests
made by wire  that are  received  prior to 3:00 p.m.  (New York  time) for Janus
Money Market Fund and Janus  Government  Money  Market Fund and 12:00 p.m.  (New
York time) for Janus  Tax-Exempt  Money  Market Fund will result in Shares being
redeemed  that day.  Proceeds of such a redemption  will normally be sent to the
predesignated  bank  account on that day,  but that day's  dividend  will not be
received. Closing times for purchase and redemption of Shares may be changed for
days in which the bond market or the New York Stock Exchange close early.

     Distributions  for all of the Funds (except Janus  Tax-Exempt  Money Market
Fund) are  taxable  income and are  subject to federal  income tax  (except  for
shareholders  exempt from income tax),  whether such  distributions are received
via wire  transfer or are  reinvested  in additional  Shares.  Full  information
regarding the tax status of income dividends and any capital gains distributions
will be mailed to  shareholders  for tax  purposes on or before  January 31st of
each year.  As described in detail in the  Prospectus,  Janus  Tax-Exempt  Money
Market Fund anticipates that  substantially all income dividends it pays will be
exempt from federal income tax, although  dividends  attributable to interest on
taxable investments, together with distributions from any net realized short- or
long-term capital gains, are taxable.

     The Funds intend to qualify as regulated investment companies by satisfying
certain requirements  prescribed by Subchapter M of the Internal Revenue Code of
1986.

     Some money market  securities  employ a trust or other similar structure to
modify the maturity, price characteristics,  or quality of financial assets. For
example,  put  features  can be used to modify the  maturity of a  security,  or
interest rate adjustment features can be used to enhance price stability. If the
structure does not perform as intended,  adverse tax or investment  consequences
may  result.  Neither the  Internal  Revenue  Service  nor any other  regulatory
authority has ruled definitively on certain legal issues presented by structured
securities. Future tax or other regulatory determinations could adversely affect
the  value,  liquidity,  or tax  treatment  of the  income  received  from these
securities or the nature and timing of distributions made by a portfolio.

MISCELLANEOUS INFORMATION

     Each Fund is a series of the Trust, a Massachusetts Business Trust that was
created on February 11,  1986.  The Trust is an open-end  management  investment
company  registered  under the 1940 Act.  As of the date of this SAI,  the Trust
consists of 20 separate series,  three of which currently offer three classes of
Shares.  The Funds were added to the Trust as  separate  series on  December  9,
1994.

     Janus  Capital  reserves  the right to the name  "Janus." In the event that
Janus Capital does not continue to provide  investment  advice to the Funds, the
Funds must cease to use the name "Janus" as soon as reasonably practicable.

                                       13
<PAGE>
     Under  Massachusetts  law,  shareholders of the Funds could,  under certain
circumstances,  be held liable for the obligations of their Fund.  However,  the
Agreement  and  Declaration  of Trust (the  "Declaration  of  Trust")  disclaims
shareholder  liability  for acts or  obligations  of the Funds and requires that
notice of this disclaimer be given in each  agreement,  obligation or instrument
entered into or executed by the Funds or the Trustees.  The Declaration of Trust
also  provides for  indemnification  from the assets of the Funds for all losses
and expenses of any Fund  shareholder  held liable for the  obligations of their
Fund.  Thus, the risk of a shareholder  incurring a financial loss on account of
its liability as a shareholder  of one of the Funds is limited to  circumstances
in which  their Fund would be unable to meet its  obligations.  The  possibility
that these  circumstances  would occur is remote. The Trustees intend to conduct
the  operations  of the Funds to avoid,  to the extent  possible,  liability  of
shareholders for liabilities of their Fund.

SHARES OF THE TRUST

     The  Trust  is  authorized  to issue  an  unlimited  number  of  shares  of
beneficial  interest  with a par value of one cent per share for each  series of
the Trust. Shares of each Fund are fully paid and nonassessable when issued. All
shares of a Fund  participate  equally in dividends and other  distributions  by
such  Fund,  and in  residual  assets of that Fund in the event of  liquidation.
Shares of each Fund have no preemptive, conversion or subscription rights.

     The Trust is authorized to issue multiple  classes of shares for each Fund.
Currently, Janus Money Market Fund, Janus Government Money Market Fund and Janus
Tax-Exempt  Money  Market  Fund each offer  three  classes of shares by separate
prospectuses.  The  Shares  discussed  in this  SAI  are  offered  only  through
Financial  Institutions that meet minimum investment  requirements in connection
with trust accounts,  cash management  programs and similar programs provided to
their customers.  A second class of shares,  Institutional Shares, is offered to
individual,  institutional  and  corporate  clients and  foundations  and trusts
meeting certain minimum investment criteria.  A third class of shares,  Investor
Shares, is offered to the general public.

VOTING RIGHTS

     The present Trustees were elected at a meeting of the Trust's  shareholders
held on July 10, 1992,  with the exception of Mr. Craig who was appointed by the
Trustees as of June 30, 1995. Under the Declaration of Trust,  each Trustee will
continue in office  until the  termination  of the Trust or his  earlier  death,
resignation,  bankruptcy,  incapacity or removal.  Vacancies will be filled by a
majority  of the  remaining  Trustees,  subject to the 1940 Act.  Therefore,  no
annual  or  regular  meetings  of  shareholders  normally  will be held,  unless
otherwise  required by the Declaration of Trust or the 1940 Act.  Subject to the
foregoing,  shareholders have the power to vote to elect or remove Trustees,  to
terminate or reorganize  their Fund, to amend the Declaration of Trust, to bring
certain  derivative actions and on any other matters on which a shareholder vote
is required by the 1940 Act, the Declaration of Trust, the Trust's Bylaws or the
Trustees.

     Each share of each series of the Trust has one vote (and  fractional  votes
for  fractional  shares).  Shares of all series of the Trust have  noncumulative
voting  rights,  which  means that the holders of more than 50% of the shares of
all series of the Trust  voting for the  election of Trustees  can elect 100% of
the  Trustees if they  choose to do so and,  in such  event,  the holders of the
remaining shares will not be able to elect any Trustees. Each series or class of
the Trust will vote  separately  only with respect to those  matters that affect
only  that  series  or class or if the  interest  of the  series or class in the
matter differs from the interests of other series or classes of the Trust.

INDEPENDENT ACCOUNTANTS

     Price Waterhouse LLP, 950 Seventeenth Street, Suite 2500, Denver,  Colorado
80202,  independent accountants for the Funds, audit the Funds' annual financial
statements and prepare their tax returns.

REGISTRATION STATEMENT

APPENDIX A
DESCRIPTION OF SECURITIES RATINGS

MOODY'S AND STANDARD & POOR'S

MUNICIPAL AND CORPORATE BONDS AND MUNICIPAL LOANS

     The two highest ratings of Standard & Poor's Ratings  Services  ("S&P") for
municipal and  corporate  bonds are AAA and AA. Bonds rated AAA have the highest
rating assigned by S&P to a debt obligation.  Capacity to pay interest and repay
principal is extremely strong. Bonds rated AA have a very strong capacity to pay
interest and repay  principal and differ from the highest rated issues only in a
small  degree.  The AA rating may be modified  by the  addition of a plus (+) or
minus (-) sign to show relative standing within that rating category.

     The two highest ratings of Moody's Investors Service,  Inc. ("Moody's") for
municipal  and  corporate  bonds are Aaa and Aa.  Bonds  rated Aaa are judged by
Moody's  to be of the best  quality.  Bonds  rated Aa are  judged  to be of high
quality by all  standards.  Together with the Aaa group,  they comprise what are
generally  known as  high-grade  bonds.  Moody's  states that Aa bonds are rated
lower than the best bonds because  margins of protection or other  elements make
long-term risks appear  somewhat larger than Aaa securities.  The generic rating
Aa may be modified by the  addition  of the  numerals 1, 2 or 3. The  modifier 1
indicates that the security  ranks in the higher end of the Aa rating  category;
the modifier 2 indicates a mid-range ranking;  and the modifier 3 indicates that
the issue ranks in the lower end of such rating category.

SHORT TERM MUNICIPAL LOANS

     S&P's highest  rating for  short-term  municipal  loans is SP-1. S&P states
that short-term  municipal securities bearing the SP-1 designation have a strong
capacity  to pay  principal  and  interest.  Those  issues  rated SP-1 which are
determined to possess a very strong capacity to pay debt service will be given a
plus (+)  designation.  Issues  rated  SP-2 have  satisfactory  capacity  to pay
principal and interest with some vulnerability to adverse financial and economic
changes over the term of the notes.

     Moody's  highest rating for  short-term  municipal  loans is  MIG-1/VMIG-1.
Moody's states that short-term  municipal  securities rated  MIG-1/VMIG-1 are of
the best quality,  enjoying  strong  protection from  established  cash flows of
funds for their  servicing or from  established  and  broad-based  access to the
market for refinancing,  or both. Loans bearing the MIG-2/VMIG-2 designation are
of high quality,  with margins of protection  ample  although not so large as in
the MIG-1/VMIG-1 group.

OTHER SHORT-TERM DEBT SECURITIES

     Prime-1 and Prime-2  are the two  highest  ratings  assigned by Moody's for
other  short-term debt securities and commercial  paper, and A-1 and A-2 are the
two highest  ratings for  commercial  paper  assigned by S&P.  Moody's  uses the
numbers 1, 2 and 3 to denote relative strength within its highest classification
of Prime,  while S&P uses the  numbers  1, 2 and 3 to denote  relative  strength
within its highest  classification of A. Issuers rated Prime-1 by Moody's have a
superior  ability for repayment of senior  short-term debt  obligations and have
many  of  the   following   characteristics:   leading   market   positions   in
well-established   industries,   high   rates  of  return  on  funds   employed,
conservative  capitalization  structure with moderate reliance on debt and ample
asset protection,  broad margins in earnings coverage of fixed financial charges
and high internal cash  generation,  and well  established  access to a range of
financial  markets and assured  sources of alternate  liquidity.  Issuers  rated
Prime-2 by Moody's have a strong ability for repayment of senior short-term debt
obligations  and display many of the same  characteristics  displayed by issuers
rated Prime-1,  but to a lesser degree.  Issuers rated A-1 by S&P carry a strong
degree of safety regarding timely repayment.  Those issues determined to possess
extremely strong safety characteristics are denoted with a plus (+) designation.
Issuers rated A-2 by S&P carry a satisfactory  degree of safety regarding timely
repayment.

FITCH

F-1+ -  Exceptionally  strong credit  quality.  Issues  assigned this rating are
     regarded as having the strongest degree of assurance for timely payment.

F-1  - Very strong  credit  quality.  Issues  assigned  this  rating  reflect an
     assurance for timely payment only slightly less in degree than issues rated
     F-1+.

F-2  - Good credit  quality.  Issues  assigned  this rating have a  satisfactory
     degree of assurance for timely payments, but the margin of safety is not as
     great as the F-1+ and F-1 ratings.

                                       16
<PAGE>
DUFF & PHELPS INC.

Duff 1+ - Highest certainty of timely payment.  Short-term liquidity,  including
     internal  operating  factors and/or ready access to alternative  sources of
     funds,  is clearly  outstanding,  and safety is just below  risk-free  U.S.
     Treasury short-term obligations.

Duff 1 - Very high certainty of timely payment.  Liquidity factors are excellent
     and  supported by good  fundamental  protection  factors.  Risk factors are
     minor.

Duff 1 - High  certainty  of timely  payment.  Liquidity  factors are strong and
     supported by good  fundamental  protection  factors.  Risk factors are very
     small.

Duff 2 - Good  certainty  of  timely  payment.  Liquidity  factors  and  company
     fundamentals  are sound.  Although  ongoing funding needs may enlarge total
     financing requirements, access to capital markets is good. Risk factors are
     small.

THOMSON BANKWATCH, INC.

TBW-1- The highest  category;  indicates a very high degree of  likelihood  that
     principal and interest will be paid on a timely basis.

TBW-2- The second highest category;  while the degree of safety regarding timely
     repayment of  principal  and  interest is strong,  the  relative  degree of
     safety is not as high as for issues rated TBW-1.

TBW-3-  The  lowest  investment  grade  category;   indicates  that  while  more
     susceptible  to adverse  developments  (both  internal and  external)  than
     obligations with higher ratings, capacity to service principal and interest
     in a timely fashion is considered adequate.

TBW-4- The lowest  rating  category;  this rating is regarded as  non-investment
grade and therefore speculative.

IBCA, INC.

A1+  - Obligations supported by the highest capacity for timely repayment. Where
     issues possess a  particularly  strong credit  feature,  a rating of A1+ is
     assigned.

A2 - Obligations supported by a good capacity for timely repayment.

A3 - Obligations supported by a satisfactory capacity for timely repayment.

B - Obligations  for which there is an  uncertainty as to the capacity to ensure
timely repayment.

C - Obligations for which there is a high risk of default or which are currently
in default.

                                       17

APPENDIX B
DESCRIPTION OF MUNICIPAL SECURITIES

     Municipal Notes generally are used to provide for short-term  capital needs
and usually have maturities of one year or less. They include the following:

     1. Project Notes, which carry a U.S.  government  guarantee,  are issued by
public bodies  (called  "local  issuing  agencies")  created under the laws of a
state, territory, or U.S. possession.  They have maturities that range up to one
year from the date of issuance. Project Notes are backed by an agreement between
the local  issuing  agency  and the  Federal  Department  of  Housing  and Urban
Development.  These  Notes  provide  financing  for a wide  range  of  financial
assistance  programs  for  housing,  redevelopment,  and related  needs (such as
low-income housing programs and renewal programs).

     2. Tax  Anticipation  Notes are issued to finance  working capital needs of
municipalities.  Generally,  they are issued in anticipation of various seasonal
tax revenues,  such as income,  sales,  use and business taxes,  and are payable
from these specific future taxes.

     3. Revenue Anticipation Notes are issued in expectation of receipt of other
types of revenues,  such as Federal revenues available under the Federal Revenue
Sharing Programs.

     4. Bond  Anticipation  Notes are issued to provide interim  financing until
long-term  financing can be arranged.  In most cases,  the long-term  bonds then
provide the money for the repayment of the Notes.

     5.  Construction  Loan  Notes are sold to provide  construction  financing.
After  successful  completion and acceptance,  many projects  receive  permanent
financing through the Federal Housing  Administration under the Federal National
Mortgage   Association  ("Fannie  Mae")  or  the  Government  National  Mortgage
Association ("Ginnie Mae").

     6.  Tax-Exempt  Commercial  Paper is a short-term  obligation with a stated
maturity  of 365 days or less.  It is  issued  by  agencies  of state  and local
governments to finance seasonal working capital needs or as short-term financing
in anticipation of longer term financing.

     Municipal  Bonds,  which meet longer term capital needs and generally  have
maturities   of  more  than  one  year  when   issued,   have  three   principal
classifications:

     1.  General  Obligation  Bonds  are  issued  by such  entities  as  states,
counties,   cities,  towns,  and  regional  districts.  The  proceeds  of  these
obligations  are  used  to  fund a wide  range  of  public  projects,  including
construction or improvement of schools,  highways and roads, and water and sewer
systems.  The basic  security  behind General  Obligation  Bonds is the issuer's
pledge  of its full  faith and  credit  and  taxing  power  for the  payment  of
principal  and  interest.  The taxes that can be levied for the  payment of debt
service  may be  limited  or  unlimited  as to the  rate or  amount  of  special
assessments.

     2. Revenue Bonds in recent years have come to include an increasingly  wide
variety of types of  municipal  obligations.  As with other  kinds of  municipal
obligations,  the issuers of revenue  bonds may consist of virtually any form of
state or local governmental entity,  including states,  state agencies,  cities,
counties,  authorities of various kinds, such as public housing or redevelopment
authorities,  and special districts, such as water, sewer or sanitary districts.
Generally,  revenue  bonds are secured by the revenues or net  revenues  derived
from a particular facility, group of facilities, or, in some cases, the proceeds
of a special excise or other specific  revenue source.  Revenue bonds are issued
to finance a wide variety of capital projects including electric, gas, water and
sewer systems;  highways,  bridges,  and tunnels;  port and airport  facilities;
colleges and universities; and hospitals. Many of these bonds provide additional
security in the form of a debt service reserve fund to be used to make principal
and  interest  payments.  Various  forms of credit  enhancement,  such as a bank
letter of credit or municipal  bond  insurance,  may also be employed in revenue
bond  issues.  Housing  authorities  have a wide  range of  security,  including
partially or fully insured  mortgages,  rent subsidized  and/ or  collateralized
mortgages,  and/or the net revenues from housing or other public projects.  Some
authorities  provide further  security in the form of a state's ability (without
obligation) to make up deficiencies in the debt service reserve fund.

     In recent  years,  revenue  bonds  have been  issued in large  volumes  for
projects that are privately owned and operated (see 3 below).

     3. Private  Activity Bonds are considered  municipal  bonds if the interest
paid thereon is exempt from Federal income tax and are issued by or on behalf of
public  authorities  to  raise  money  to  finance  various  privately  operated
facilities for business and manufacturing,  housing and health.  These bonds are
also used to finance public  facilities  such as airports,  mass transit systems
and ports.  The payment of the principal and interest on such bonds is dependent
solely on the ability of the facility's  user to meet its financial  obligations
and the pledge,  if any,  of real and  personal  property  as security  for such
payment.

     While, at one time, the pertinent  provisions of the Internal  Revenue Code
permitted private activity bonds to bear tax-exempt  interest in connection with
virtually  any type of  commercial  or  industrial  project  (subject to various
restrictions as to authorized costs,  size limitations,  state per capita volume
restrictions,  and other  matters),  the types of qualifying  projects under the
Code

                                       18
<PAGE>
have become  increasingly  limited,  particularly since the enactment of the Tax
Reform Act of 1986. Under current provisions of the Code,  tax-exempt  financing
remains available,  under prescribed conditions, for certain privately owned and
operated rental multi-family housing facilities,  nonprofit hospital and nursing
home projects,  airports, docks and wharves, mass commuting facilities and solid
waste  disposal  projects,  among others,  and for the  refunding  (that is, the
tax-exempt  refinancing) of various kinds of other private  commercial  projects
originally  financed  with  tax-exempt  bonds.  In  future  years,  the types of
projects  qualifying  under the Code for  tax-exempt  financing  are expected to
become increasingly limited.

     Because  of  terminology  formerly  used  in  the  Internal  Revenue  Code,
virtually  any form of  private  activity  bond may still be  referred  to as an
"industrial  development  bond," but more and more frequently revenue bonds have
become  classified  according to the particular type of facility being financed,
such as hospital revenue bonds, nursing home revenue bonds, multi-family housing
revenue bonds,  single family  housing  revenue  bonds,  industrial  development
revenue bonds, solid waste resource recovery revenue bonds, and so on.

     Other Municipal Obligations,  incurred for a variety of financing purposes,
include:  municipal leases, which may take the form of a lease or an installment
purchase or conditional sale contract, are issued by state and local governments
and  authorities to acquire a wide variety of equipment and  facilities  such as
fire and  sanitation  vehicles,  telecommunications  equipment and other capital
assets.  Municipal leases frequently have special risks not normally  associated
with general  obligation or revenue bonds.  Leases and  installment  purchase or
conditional sale contracts (which normally provide for title to the leased asset
to pass  eventually  to the  government  issuer)  have  evolved  as a means  for
governmental  issuers to acquire  property  and  equipment  without  meeting the
constitutional  and  statutory  requirements  for  the  issuance  of  debt.  The
debt-issuance limitations of many state constitutions and statutes are deemed to
be  inapplicable  because  of the  inclusion  in many  leases  or  contracts  of
"non-appropriation"  clauses that provide  that the  governmental  issuer has no
obligation to make future  payments under the lease or contract  unless money is
appropriated for such purpose by the appropriate legislative body on a yearly or
other periodic basis. To reduce this risk, the Fund will only purchase municipal
leases subject to a  non-appropriation  clause when the payment of principal and
accrued interest is backed by an unconditional  irrevocable letter of credit, or
guarantee  of a bank or other  entity that meets the  criteria  described in the
Prospectus.

     Tax-exempt bonds are also categorized  according to whether the interest is
or is not includible in the calculation of alternative  minimum taxes imposed on
individuals,  according  to whether the costs of acquiring or carrying the bonds
are or are not deductible in part by banks and other financial institutions, and
according to other criteria relevant for Federal income tax purposes. Due to the
increasing   complexity  of  Internal  Revenue  Code  and  related  requirements
governing  the issuance of  tax-exempt  bonds,  industry  practice has uniformly
required,  as a condition to the issuance of such bonds,  but  particularly  for
revenue  bonds,  an  opinion of  nationally  recognized  bond  counsel as to the
tax-exempt status of interest on the bonds.

ITEM 27.  Indemnification

     Article VIII of Janus Investment  Fund's Agreement and Declaration of Trust
provides for  indemnification  of certain persons acting on behalf of the Funds.
In general,  Trustees and officers  will be  indemnified  against  liability and
against all  expenses of  litigation  incurred  by them in  connection  with any
claim,  action,  suit or  proceeding  (or  settlement of the same) in which they
become  involved  by  virtue of their  Fund  office,  unless  their  conduct  is
determined to constitute  willful  misfeasance,  bad faith,  gross negligence or
reckless  disregard of their duties,  or unless it has been determined that they
have not acted in good faith in the reasonable belief that their actions were in
or not opposed to the best interests of the Funds. A determination that a person
covered by the indemnification  provisions is entitled to indemnification may be
made by the court or other body before which the  proceeding  is brought,  or by
either a vote of a majority of a quorum of Trustees who are neither  "interested
persons" of the Trust nor parties to the proceeding or by an  independent  legal
counsel  in a  written  opinion.  The  Funds  also may  advance  money for these
expenses,  provided that the Trustee or officer undertakes to repay the Funds if
his conduct is later determined to preclude indemnification,  and that either he
provide

security for the undertaking, the Trust be insured against losses resulting from
lawful  advances  or a  majority  of a  quorum  of  disinterested  Trustees,  or
independent counsel in a written opinion,  determines that he ultimately will be
found to be entitled to  indemnification.  The Trust also  maintains a liability
insurance policy covering its Trustees and officers.

               its  obligations   under  this  Agreement  as  the  Trustees  may

misfeasance,  bad faith or gross negligence in the performance of its duties, or
by reason of reckless  disregard of its  obligations  and duties  hereunder  and
except to the extent  otherwise  provided  by law.  As used in this  Section 12,
"JCC" shall  include any  affiliate of JCC or any other  person  retained by JCC
performing services for the Trust contemplated hereunder and directors, officers
and employees of JCC and such affiliates or any such person.

to be  deemed to be  exclusive,  and JCC and its  affiliates  are free to render
services  to  other  parties.  It is  understood  that  Trustees,  officers  and
shareholders  of the Trust are or may  become  interested  in JCC as  directors,
officers and  shareholders  of JCC,  that  directors,  officers,  employees  and
shareholders  of JCC are or may become  similarly  interested in the Trust,  and
that JCC may become interested in the Trust as a shareholder or otherwise.
